00:00 Animals can be pretty amazing and evolution has given some of them extremely cool abilities
00:08 that let them survive in extremely wild situations.
00:11 The Society for Integrative and Comparative Biology reports 60% of Alaskan wood frogs
00:16 let their bodies freeze solid every winter.
00:19 They do this by building up massive amounts of glucose in their organs, a protectant against
00:23 the formation of ice crystals that would otherwise damage their cells.
00:27 Similar to the protein found in the blood of Nautithenoid fish, which binds to ice crystals
00:31 that try to form while a fish inhabits waters that sit around 28 degrees.
00:35 Meanwhile those frogs cousins, the Cyclorana Australis frog, create mucus cocoons to wait
00:40 out particularly hot and dry periods.
00:43 Then you have the Okapi, perhaps Congo's strangest looking creature, their feet also have glands
00:47 that spread a musky substance to mark their territory.
00:50 Still one of the more impressive abilities visually must be the Cuttlefish.
00:54 Their camouflaging skills allow them to not only change their color to blend in with their
00:57 surroundings but they can also change the texture of their bodies as well.
01:01 Cuttlefish have an estimated 10 million chromatophores or tiny pigmented skin cells each controlled
01:06 separately, allowing them to take on the guise of just about any underwater structure.
