00:06the stories you're about to see are real terrifying home invasions and tyrants
00:18fighting to end all competition these clashers and crashers ignore boundaries
00:24and battle to the death we're counting down the 10 most intense deadly duels on weird true and freaky
00:40two bitter rivals face off and these odds could equal some sweet revenge
00:50serengeti tanzania here east africa's watering holes are a vital resource for some of the
00:57world's largest animals but they're also a dangerous hunting ground for a prehistoric
01:04predator the nile crocodile now crocodiles are ferocious predators they can reach up to 20 feet
01:111600 pounds they attack their prey by using the element of surprise they grab the prey drag it
01:19underwater and dismember it or drown it near the banks of a river a nile croc slowly makes its way
01:27through the water hunting a meal but as it stealthily swims under the surface it makes a big mistake
01:35this croc's not alone it's entered the territory of 30 adult hippos the croc does its best to keep
01:46hidden but when a hippo senses its presence underwater all hell breaks loose
01:56the reptile thrashes trying desperately to flee but it's trapped and outnumbered
02:04they are going for us to get out of our space getting out of this mess will be nearly impossible
02:13hippos might be herbivores but they're extremely dangerous they're so aggressive the crocodiles
02:19usually stay away but when the rain stop the water starts to dry up and hippos and crocs compete for
02:26the same space and that's when things get really violent suddenly the croc slips under and the action
02:34stops unseen and submerged this may be its only chance there he is but then
02:45got it when the croc comes back up for air the hippos spot the predator and attack clamping down
02:53one of the hippos lifts the croc up out of the water it tears into the reptile's tough exterior
03:01got him big time hippos canine teeth are over a foot long each they can snap a canoe in half
03:08with just
03:09one chunk the crocodile's skin is like armor plating but that's no match for a hippo
03:17but a last-ditch move changes everything the croc manages to bite one of the massive behemoths
03:25creating a commotion and a chance to escape wriggling free it slips under the water again
03:34out of the jaws of death it's a missed opportunity for the hippos but they've shown this croc who's boss
03:42in this watering hole next in our deadly dual countdown is number nine sending the wrong signals
03:55could get you into deep trouble
04:01st mark's river florida each morning fishermen head to these waters to haul in a catch
04:08fish and commune with local wildlife including often ill-tempered geese these are large migratory
04:16waterfowl that live on rivers lakes and ponds they eat mostly vegetation and insects but they also eat
04:23small fish on a day like any other pro angler drew Gregory's out on the river with fellow fishermen
04:31catching lines and reeling in plenty of fish recording everything on a camera connected to
04:38his kayak drew decides to throw one of his smaller catches to a hungry river resident nearby
04:47for drew it's a kind gesture but the goose doesn't see it that way little does drew know he's just
04:55issued a challenge geese are very territorial and can be extremely aggressive even if offered food
05:02they might not take it as a gracious gesture they kept moving closer and closer to me and the big
05:09one
05:09starts getting very brave and it starts investigating around my kayak and nipping at my fishing lures I'm
05:14like hey man stay away I want to catch fish not geese suddenly the goose attacks I feel these legs
05:26and
05:26wings and limbs all over my back just jumping on me like crazy and I had no clue what it
05:30was or what
05:31was happening even though geese only weigh about 10 pounds they have very strong solid wings and if
05:37they want to jump and attack they will use those wings to beat against whatever it is including a
05:42predator or a human that just might be in the wrong place at the wrong time then the goose knots
05:51drew
05:51off balance toppling him over straight into gator territory and fighting his way back to the edge of
06:02his kayak drew realizes he can't get back in gooses squawking and honking and just going nuts
06:12and I'm just gagging trying to catch my breath I started thinking I know the gators typically
06:17don't bother you but I'm sitting here flailing this could be a much worse incident here today
06:24this type of commotion often attracts alligators because they think it's prey struggling so he needs
06:30to get out of that water immediately just when all seems lost one of Drew's fishing buddies paddles
06:38over in the nick of time and helps him upright to safety that wasn't hurt from the incident other
06:46than you know my ego so we kept fishing and we floated our way down the river for the rest
06:50of that
06:50day and we said we've got to share this to the world
06:58before we get to the next story in our deadly dual countdown when you enter the ring with this
07:05miniature scrapper you'd better come prepared or else
07:17this busy city is a center for medicine science and education but not all the city's residents are
07:26here to learn like most crowded urban areas rodents are a constant problem rats congregate in urban
07:35environments because urban environments provide everything rats love lots of food debris water
07:43shelter so being in a dense urban environment provides the perfect environment for them to
07:50get everything they need and also have quick getaways on a quiet morning 20 year old student to we side
08:00is sweeping debris from a hole near her apartment when a giant road suddenly enters the pit and goes on
08:08the
08:08attack trapped and afraid the young student swats again and again but the rat dodges each time then he
08:21tries a new tactic an aerial assault bearing his teeth the rodent flies through the air jumping with
08:32shocking strength for such a small pest rats can jump about two and a half feet up in the air
08:40and they
08:41can jump outward about four feet so that's pretty good they have some powerful back legs and they can
08:47also run fairly fast but this rat is just as afraid of the woman as she is of him he
08:56suddenly runs toward a
08:58corner of the pit looking for a way out in this momentary ceasefire an onlooker extends his hand down to
09:09the
09:09woman it's a chance to escape
09:14that goes horribly wrong
09:20now two people are stuck in the pit with the unstoppable rat
09:27the man quickly hoists himself to safety leaving the rat in hot pursuit of the terrified woman
09:33alone helpless and cornered by the charging vermin a filthy rodent bite seems inevitable they are carrying
09:42diseases that they can give to humans which are zoonotic diseases and they do carry some pretty
09:49significant zoonotic diseases that humans can catch some of those are things like plague hantavirus
09:59tularemia rat fight fever
10:07fortunately the somewhat comical encounter ends without injury later twee's able to laugh it off but
10:15hopefully next time she'll remember never bring a broom to a fight with this feisty rat
10:26next in our deadly duel countdown is number eight
10:32with this home invader roaming the neighborhood you should always watch your back
10:41Colorado springs Colorado sitting at the base of the rocky mountains this vibrant town overlaps with wild
10:50nature and anywhere the two worlds intersect there's the potential for encounters with a variety of
10:57animals from white-tailed deer to opportunistic black bears black bears are mostly scavengers they
11:07fully have the capability of hunting and chasing down animals for food but that takes a lot of
11:12effort in urban areas they're gonna eat whatever is easiest to come upon most likely your garbage or
11:19whatever dog food or cat food gets left outside
11:23up in the hills above town danielle backstrom arrives home and pulls into her garage
11:31and just when she's about to exit her vehicle she discovers she's not alone
11:41in a state where over 17 000 black bears roam one of the hungry predators has slipped in when she
11:48wasn't
11:48looking and now he doesn't seem like he's going to leave he's on the hunt for an easy meal and
11:56it's a
11:57dangerous trend when bears start associating us with food there's almost no going back habituation is when a wild
12:06animal gets used to humans being around and a wild animal that's not afraid of people is way more
12:12dangerous than a wild animal that is they're going to go to the wrong person at the wrong time and
12:17either the bear is going to get killed or the person is shoot bear shoot the situation is getting serious
12:27if the bear doesn't want to leave there's very little danielle can do um i can't go because
12:33there is a bear behind me come on bear move putting her car in reverse she tries to nudge the
12:39bear
12:40slowly out but he only moves side to side not away oh my god trapped and afraid danielle has no
12:51way out
12:54normally if you encounter a black bear in the wild you want to be very loud and be as big
12:59as you can
13:01in this situation this woman is trapped in her car and is of no threat to the bear at all
13:06it's not
13:07afraid of humans because at this point it's probably learned they don't do anything to it bear
13:13here he is in the ring of your mirror then she gets an idea pulling her car forward let me
13:19see if i
13:20close it if he'll she quickly hits the button to close her garage there he goes he's walking away
13:28successfully locking the bear out shutting the door on this furry intruder
13:37we return to our deadly deer countdown with number seven
13:42golf is tough enough without this dangerous hazard
13:49palmetto florida this coastal town on the gulf of mexico has a subtropical climate perfectly suited
13:57for an array of reptiles but the biggest and possibly the meanest is the american alligator and they
14:06don't always stay in the swamp in florida we have this interesting situation where we get alligators
14:12overlapping with humans a lot and it's because humans are continually sort of claiming this habitat
14:18that these alligators live in and these alligators are not shy
14:22that's why at a local golf course a foursome halts their game when a mammoth alligator slowly saunters
14:29across the fairway that is the biggest freaking alligator i've ever seen in my life
14:39it must be 15 feet long this gator nicknamed chubs for obvious reasons has become a celebrity here
14:52at the course moving between ponds on the third eighth and 14th holes he's definitely chosen this
15:00as his hunting ground you gotta be kidding me the average size for a male is around 11 feet this
15:08one
15:08is obviously way bigger than that it's huge so if this guy has claimed this golf course as its territory
15:13that's a big problem and people would definitely want to steer clear of that guy american alligators
15:20max out at about 15 feet long and 1 000 pounds making chubs potentially as big as they come
15:30what he hunts at a golf course that could feed his incredible size isn't clear a golfer seems like
15:37a normal meal for this behemoth dude watch out man then one of the men makes a bold move
15:47to capture a better shot of the massive beast he walks closer what are you doing
15:54a predator this large is definitely best observed from far away most of the time they look like
16:02they're sort of these lumbering animals that are moving kind of slow i think people can get the wrong
16:07idea they can be really dangerous up close they can move extremely rapidly
16:14thankfully the huge animal isn't interested in a savory snack at the moment
16:20in fact according to golf course staff this alligator and others have been living peacefully in their ponds for
16:28for a long time still if your ball ever lands near a water hazard at this course you should consider
16:36it
16:36lost that is a monster our countdown will continue in a moment but first
16:45in this duel of three against one fortune may not be enough to save this brave bird
16:57zhuzhang province china here the hangzhou safari park is known for exotic animals
17:04like giant pandas golden monkeys and white rhinoceros but today tourists witness and especially rare sighting
17:15wild red crown cranes soaring high in a strong crosswind red crown cranes are one of the largest crane
17:24species they can stand up to five feet tall and have as much as an eight foot wingspan which is
17:30pretty
17:30large it does take them a little bit of effort to get off the ground because of their
17:34large size they need to be able to get somewhat of a running start
17:40then disaster
17:43blown by the wind one of the cranes has come down right in the middle of one of the park's
17:48deadliest enclosures the siberian tigers three in total
17:55with no room to run and take off the crane is forced to confront the deadly predators
18:02he charges the big cats in an unbelievable display of courage and desperation but this bluffing
18:10strategy will only work for so long one swat from an enormous siberian tiger and the beautiful bird will
18:18be dead when red crown cranes are frightened they usually go into a defensive posture they're going to
18:25try to bluff or scare the predator away they'll spread out their eight foot wingspan to look twice as large
18:31as they actually are
18:35after a few false charges from the crane the tigers turn the tables charging back at the bird
18:43instinctually the crane runs a dangerous trigger for a deadly big cat instinct because the tigers have a
18:51strong predatory chase instinct as soon as the bird does turn around the tigers go right after it
18:58then out of nowhere the tigers retreat distracted by a gift of food from the zoo keepers the park
19:06visitors breathe a sigh of relief as the majestic bird is ushered out of the enclosure it turns out
19:13fortune really does favor the brave
19:20our deadly dual countdown continues with number six
19:25in this dysfunctional family just being born can get you killed
19:34atasha national park namibia
19:38these planes bear witness to nature's most ancient balancing act between hunter and hunted
19:45but thinning the herd isn't always a battle of predator versus prey sometimes a new alpha trying to take
19:53over is the biggest threat even one is seemingly noble as the striped zebra in the wild zebras exist as
20:01harems which consist of one dominant male a number of females and their offspring fights among zebra males
20:08can be brutal and very violent they are fighting for access to mates so everything is at stake
20:16on safari a group of tourists stumbles upon a terrifying scene an adult male zebra has pinned a young colt
20:25under water the youngster's mother stands by completely helpless it's almost impossible for her to
20:33overpower the male one-on-one the mother can't watch her baby die
20:44she charges the large male creating a brief opening for the colt to escape
20:51but the stallion refuses to relent and sends a wicked kick in the direction of the mother
20:58when a new male takes over a harem he will systematically kill all of the babies that females
21:04are still nursing this allows the females to come back into estrus so they're sexually receptive
21:09and the male can then father offspring of his own
21:17the youngster but the foal manages to slip out the wolf will help from ma he runs for his life
21:26but the chase doesn't last long fallen with its undercarriage exposed one blow from the stallion's
21:34hooves will end this foals life. Zebra stallions are very aggressive they can
21:42weigh up to 800 pounds and a single kick can break a lion's jaw in two so even
21:48big cats avoid stallion zebras. But then the young zebra's mother makes a last
21:56ditch effort to save her child. The female rams and rams again creating just enough
22:06distance for the colt to slip away for now. It's an incredible example of a
22:12desperate mother's unbeatable drive to nurture and defend no matter the odds.
22:22Before we continue our countdown maternal instinct is put to the ultimate test.
22:28Can mother's milk feed a mortal enemy?
22:35Russia. In the far east of the country in centuries past the cold desolate plains
22:42were a battleground for two expert predators wolves and Siberian tigers. These two were
22:51never meant to play nice. Dogs were domesticated about 15,000 years ago and
22:58cats were domesticated about 9 or 10,000 years ago and what we've done is we've
23:03sort of forced dogs and cats to live together so that's why sometimes our
23:07dogs and cats don't get along so well. But here in an ordinary Russian home a
23:15bizarre situation unfolds. A newborn Cornish Rex cat named Eli sucks milk from
23:22what seems to be her mother's teeth. But look again that's not her mother. This
23:32curly-haired wet nurse is a poodle named Barsic.
23:41While some dogs tolerate and even seem to befriend cats feeding a kitten their own
23:47milk is another story. A story you have to see to believe. When a mammal is nursing
23:54her young a hormone called oxytocin is released. That hormone is known as the
24:00happy hormone. So one could infer that it would be enjoyable for this mammal to be
24:07nursing her young. This abnormal cross-species rearing could have deadly
24:13consequences. If this little kitten bites too hard onto Barsic's teat instinct could
24:20take over. But the power of a mother's instinct to nurture even nurse a foe is more
24:27powerful than any rivalry. The kitten keeps on feeding and Barsic the poodle seems
24:34perfectly at peace. Showing above all love truly knows no boundaries.
24:44We return to our deadly dual countdown with number five. A river overrun turns a casual day of boating into
24:54a fierce battle.
24:55Oh my god!
24:58Terre Haute, Indiana. A town nestled next to the Wabash River. This 500-mile waterway is a lifeline to dozens
25:08of fish species including crappie, catfish, and the notorious and destructive silver carp.
25:16Brought over from Asia in 1973 they've been causing havoc ever since.
25:23They were introduced in America as a way to help deal with algae problems in municipal waterways. Now they're a
25:30real problem in streams and rivers around the country.
25:32They're pushing out the species that are supposed to be in that area. They're out competing them.
25:37On a casual day trip, a group of locals get way more than they bargained for.
25:46While parked along the edge of the river, all around them, silver carp are leaping out of the water and
25:52landing in their boat.
25:56Silver carp are sometimes called the flying carp because they can jump really high, up to ten feet out of
26:01the water.
26:01And they're doing that to evade predators. They'll jump on masks. There's schools of them. They'll all start jumping.
26:08Oh, there they go again!
26:10Then, things get out of hand.
26:13He's so .
26:14The water erupts. More carves start launching. Each one weighs more than a bowling ball, up to 40 pounds. It's
26:25a brutal barrage.
26:26Oh, damn! What the hell?
26:29Worried they're in too deep.
26:32Oh, no!
26:34The boaters start the motor and hit the gas.
26:37Oh, my .
26:39Speeding away, the noise and vibrations of the motor cause even more fish to jump.
26:45Oh, my .
26:48And as more fish lift off, the odds of getting seriously injured by a flying fish increase exponentially.
26:56You're moving very fast. The fish leaps up. You hit the fish. You're going to get injured.
27:01There have been documented cases of people being injured. I think a boy broke his jaw.
27:05Anything that's in the air, if you're moving 30 miles an hour and you hit it, it's dangerous to you.
27:10You've got to hold both of them.
27:12Fortunately, the boat clears the carp-filled waters, and the boaters make it out safely.
27:19Oh, there they go again!
27:22Our deadly dual countdown continues.
27:25But first, an interspecies exchange with this muscular brute could end in battle.
27:36Bali, Indonesia. At the Bali Zoo, thousands of people visit daily.
27:42And a popular attraction here are the sometimes ornery orangutans.
27:50The flaps on the sides of the male orangutan's face are called flanges.
27:54And some males develop flanges during their lifetime and others never do.
27:59The males who have the flanges are more aggressive and have higher testosterone levels than the males who don't.
28:05They are signals to other orangutans he may be dominant.
28:09They may also be signals to females that he would be a good mate.
28:15Thirty-eight-year-old Jackie is the park's most famous orangutan.
28:20He's known for tossing food and even feces at park guests.
28:25But one visitor isn't afraid.
28:28He has a plan in mind that goes against any normal zoo's simplest rule.
28:33Don't feed the animals.
28:35But this man wants to prove that, like us, all primates have the capacity for sharing.
28:43He carefully lifts up a piece of fruit, aims, and tosses it across the narrow moat, right at the giant
28:52primate.
28:53For an alpha male primate like this orangutan, we shouldn't even be looking them directly in the eyes
28:59because that's considered to be a threatening gesture.
29:02We should never throw anything at them.
29:05But the first part of his plan actually works.
29:09The orangutan catches and eats the offering.
29:15There's no sharing without an exchange.
29:18So extending his arms, the man gestures for the orangutan to return the favor.
29:23With nothing but a narrow moat between them, the man could be pushing his luck too far.
29:30Orangutans are very agile and strong and can easily jump five or six feet.
29:35He may not know it, but this guy is putting himself and maybe others in extreme danger.
29:47Luckily, this time, Jackie seems to get the spirit of the gift he's been given.
29:52In an amazing display of interspecies communication, he gently tosses a piece of fruit back in return.
30:01And while you should never do this at any zoo, it's evidence that man and ape may be more alike
30:08than we realize.
30:13Next, in our deadly dual countdown, is number four.
30:19Interfere with this sushi lover's meal, and you might not live to regret it.
30:30Petropavlovsk, Russia.
30:33All along the coast, fishing vessels line the docks.
30:37These sturdy ocean vessels carry massive hauls of seafood.
30:41A huge temptation for some very big and bold ocean mammals.
30:47Sea lions.
30:49Sea lions are very efficient hunters, but they're also lazy too.
30:52They're going to pick up an easy meal whenever and however they can.
30:55So they'll do things like follow fishing boats and grab fish as they fall out of the nets
30:59or any fish that are thrown overboard they'll catch.
31:03Stepping away from their boat after a day's work,
31:06some exhausted fishermen return back to discover a huge problem.
31:11A massive sea lion has stepped on board their fishing vessel,
31:15and the hungry animal doesn't seem like it's going to leave until he gets a meal.
31:22Sea lions may seem playful and friendly,
31:26but a full-grown male can get bigger than a grizzly bear.
31:30Barking continuously, the crew's dogs may be biting off more than they can chew.
31:36Sea lions have several defenses, one of them being they have very sharp teeth and claws,
31:40and their bites are pretty extreme.
31:43They also are very heavy.
31:45They can weigh up to a ton, and they can throw themselves on anything that's attacking them.
31:50Nasty.
31:50The barking dogs are getting more and more agitated,
31:55putting the enormous sea lion into fight or flight mode.
31:59But which one he'll choose isn't clear.
32:05Then, one of the fishermen attempts to soothe the ocean creature with a tasty treat.
32:11A small fish from the day's catch.
32:14And it's a very bad idea.
32:19The sea lion decides the aggressive dogs are simply getting in the way of his meal.
32:27He reaches down, grabs a dog with his powerful jaws,
32:32and flings it more than 30 feet out of the boat.
32:36Sea lions are really, really strong.
32:38They're also really, really big.
32:40So, when a sea lion and a dog are competing for food, the sea lion's going to win.
32:47Amazingly, after flying through the air and crashing into the dock, the dog is okay.
32:54Without a doubt, he'll remember, you should never get between a hungry seafood connoisseur and a fresh catch.
33:04We continue our deadly duel countdown with number three.
33:11Here's a deadly duel where the rat rules.
33:16Moscow, Russia.
33:18In many cities throughout the country, the urban jungle is home to notorious disease-carrying rats and dangerous predatory felines.
33:29These two have been mortal enemies for thousands of years.
33:33The cat is a very good predator.
33:36It's a killing machine.
33:37It can get all kinds of rodents and birds and normally is very, very efficient at killing these guys.
33:44And rats would normally be quite terrified.
33:47Here, in a deserted alley, a city-dwelling rodent is enjoying a stroll along the edge of a fence.
33:54And it's heading straight toward a gang of feral felines.
34:01It seems like a stroll to certain death.
34:05Rats have an extraordinary ability to smell and to hear.
34:11Their sense of smell is like 60 times better than ours.
34:15So they can hear or smell the cat coming from a long way off.
34:20It would normally escape, but in fact, in this case, the very opposite is happening.
34:25Perhaps it's got a family just on the other side of the fence.
34:29One of the cats makes the first move.
34:34Stalking its unsuspecting prey.
34:39But as soon as the cat comes close,
34:43The rat does something truly shocking.
34:48Instead of flight, it chooses fight.
34:51Lunging violently at the cat, forcing her to retreat.
35:00Despite the danger, the rat keeps on charging.
35:04Again.
35:05And again.
35:07And his furious assault may have gone too far.
35:14Now, he's totally surrounded by the predators.
35:17And there's no way to know why he's taken such a deadly risk.
35:21This is a very odd behavior for a rat.
35:24Something appears to be affecting this rat in a different way from what you would normally expect.
35:29Perhaps there's something going on with its brain that's not normal.
35:33There's an organism called toxoplasmosis that can insist in the brain and cause strange behavior.
35:41But this rat will not be beaten.
35:44Gnawing, clawing, and striking mid-air.
35:50The rat scares off the felines, creating an opening for an unlikely escape.
35:58Before revealing what's next in our deadly duel countdown.
36:03It's a contest for India's most dangerous creature.
36:08The mighty cobra, or the king of the coop.
36:16Andhra Pradesh, India.
36:19Home to 50 million people.
36:21And a huge array of dangerous wildlife.
36:24Residents here must watch out for predatory tigers.
36:28Territorial elephants.
36:30And venomous king cobras.
36:33What are some of the deadliest animals in India?
36:36Well, what comes to mind are Bengal tigers, crocodiles, or elephants.
36:41But in fact, it's venomous snakes.
36:44They kill up to 50,000 people a year.
36:49On a normally quiet street, a war is raging.
36:54It's a baby king cobra, squaring off against an ordinary rooster.
37:03The cobra lunges once.
37:06Twice.
37:08Three times.
37:09But the rooster doesn't take the hint.
37:15Then, he snatches the killer reptile.
37:18It's a daring move.
37:20But it could be a death wish.
37:23Roosters have spurs on the backs of their legs.
37:27And they have their beak, which is very sharp.
37:31But they really are no match for a king cobra.
37:34Even as babies, king cobras can deliver a deadly bite.
37:42The serpent slithers back toward the roost.
37:45And the rooster follows, snatching it again.
37:49This time, the rooster carries the cobra even further from his flock.
37:54But this battle isn't over.
38:01While he holds the cobra in his beak, it strikes.
38:07And this time, it seems to connect with the rooster.
38:12Our courageous cock could already be a dead bird walking.
38:19In the world of deadly snakes, king cobras can hold their own.
38:25One bite from a king cobra can kill 20 adult human beings.
38:31It can also take down an entire elephant within a couple hours.
38:35So, it's nothing to joke about.
38:41That's when the rooster does the unthinkable.
38:45Desperate to finish the duel, he snatches up the serpent and swallows.
38:52It's a shocking display of brutality from an ordinary farm animal.
38:57A cock could replace cobras as India's most dangerous beast.
39:06Next, in our countdown of deadly duels, is number two.
39:12When an unidentified flying object swoops down on our ancient ancestor,
39:18will there be peace?
39:20Or war?
39:25Arnhem, Netherlands.
39:27The Royal Burger Zoo is one of the country's biggest animal parks.
39:32It houses an array of animals, and some of its most beloved residents
39:37are the highly intelligent chimpanzees.
39:41Chimpanzees are a source of constant interest for people
39:43because they're so similar to us in their intelligence, communication, and tool use skills.
39:49They use rocks to break open nuts, twigs to find insects and honey.
39:54Today, a television crew's filming at the zoo.
39:59And to capture a stunning view of the chimpanzee enclosure,
40:02they use a camera drone.
40:06Cruising it close to 30 feet off the ground,
40:08the drone slowly passes over,
40:11while several of the chimps stare with curiosity and concern.
40:17None of the apes is more interested than Tushi, a full-grown female.
40:22Sitting high up on the structure, she's sizing up the potential threat,
40:27and she's not empty-handed.
40:30Chimpanzees are highly territorial and would give up their lives in order to protect their territory.
40:36They regularly patrol the perimeter of their territory
40:40and viciously attack any intruders that they perceive as threats.
40:46As the drone flies to within feet of the determined primate,
40:50she swings hard and misses.
40:54The missed opportunity only fuels Tushi's anger,
40:57but the drone is nearly out of reach.
41:00Chimpanzees are intelligent and good with tools,
41:03but precision is not necessarily their strong suit.
41:05It's going to be hard for this chimpanzee to hit a target flying in the air.
41:11Tushi takes one last swing and hits.
41:15She strikes the drone out of the sky,
41:18and as it tumbles to a stop,
41:21Tushi's right there to make sure this aerial invader
41:24won't bother her troop ever again.
41:31We're almost ready to reveal our story number one.
41:35But first,
41:37in this deadly duel,
41:39it takes all the right moves to catch a meal.
41:46Sabah, Malaysia.
41:48With a warm climate and beautiful ocean views,
41:51it's a nature lover's paradise.
41:54So it's no wonder why a very special kind of snake makes its home here,
41:58among the lush rainforest canopy.
42:02The paradise tree snake.
42:04The paradise tree snakes are also known as flying snakes,
42:08because they actually glide through the air.
42:10They're almost always up in trees.
42:12They'll go for birds,
42:14they'll go for small mammals,
42:15they'll go for reptiles,
42:17anything they can get their teeth around, they'll go for it.
42:22Luckily,
42:24gliding isn't the only special skill these snakes have.
42:28Unbelievably,
42:30high above street level,
42:31one of these incredible predators that slithered into the city
42:34is cruising along a high voltage power line
42:37with the delicate grace of a highly trained circus performer.
42:44And this balancing act is not just for show.
42:47This snake is stalking a potential meal.
42:51A bird on the wire.
42:53What looks like a little spider hunter.
42:58The bird's not just going to sit and wait to become dinner.
43:01With the power of actual flight,
43:04he could evade the predator by simply lifting off.
43:07Yet for some reason,
43:09he stays.
43:10He seems like he doesn't believe the snake can actually catch him.
43:15And the serpent isn't wasting the opportunity.
43:19He's trying to get in position for a strike.
43:24Then, the bird makes a seemingly suicidal move.
43:28He swoops in, just inches from the snake.
43:32It's the predator's best chance to grab dinner.
43:35The bird is definitely gambling.
43:37It's definitely gambling.
43:39And the snake, it can definitely take this bird down.
43:41It's a prey item.
43:42And that bird sees exactly where the snake is.
43:45So it's almost mocking the snake a little bit.
43:50But the snake can't strike in time.
43:53And the bird finally decides the risk is too high.
43:58In the end, no amount of fancy moves will guarantee a full belly.
44:08We're finally ready to reveal our deadly duel number one.
44:15Sometimes, our own worst enemy
44:19is on the inside.
44:21That's a good one.
44:22Yeah.
44:24Papua, Indonesia.
44:25In this lush environment,
44:28the ecosystem's incredibly diverse.
44:31Here, animals big and small thrive.
44:34And one of the biggest and deadliest of the small
44:38is the praying mantis.
44:42Praying mantises are pretty high up in the food chain.
44:45Because they're predators,
44:46and they'll take down basically anything they can impale
44:49with their raptorial claws.
44:51They're really large-bodied insects
44:53with a pretty big abdomen that they use for laying eggs.
44:57This massive predator sits at the top of the insect food chain.
45:01But she's not without enemies.
45:04And here, in this ordinary bowl of water,
45:07an invasion has already happened on the inside.
45:13Whoa.
45:14Are you kidding me?
45:18A slender black thing slowly slips out of the mantis's abdomen.
45:24And at first, it's not clear what's happening.
45:27But while the mantis struggles to get out, it's no use.
45:32There's no way to escape this invader.
45:34A deadly parasite known as the horsehair worm.
45:40The horsehair worm needs water to reproduce, so it has to lay its eggs back in water again.
45:45It releases chemical signals to the host's brain that make the host, the praying mantis, seek out water.
45:52Because water is where the horsehair worm wants to go.
45:57With each centimeter of worm that comes out, it's hard to imagine what could be left inside this mantis's body.
46:05And yet it still moves, fighting to free itself.
46:09You've never seen anything so gross in your life.
46:12And as the last bits of worm wriggle out of his body, it's not just one,
46:18but three in total.
46:21Hey, come here.
46:22Come here, we want to save you.
46:25With each passing moment, the giant insect gets weaker and weaker.
46:30Because horsehair worms take up so much nutrients from the host as they're growing inside of it,
46:35the host almost always dies, but not 100% of the time.
46:40It might be too late for this guy.
46:42Unfortunately, this time, the praying mantis doesn't survive the grotesque invasion.
46:50Within weeks, the adult worm will lay more eggs that will one day infect a new host,
46:57ensuring that this circle of painfully disturbing life continues.
47:03Whoa, are you kidding me?
47:07They're frightening, fierce, and always alarming.
47:11Help him!
47:12Insane, deadly duels that show.
47:14In wild nature, there are no boundaries.
47:17And there's always more to come on weird, true, and freaky.
47:23God, it's big time.
