1,000,000 Hairs Per Inch: How a Sea Otter Survives Ice Water

💰 Support the channel: USDT TRC20: TBebXWjFeAJHfArVsJvt8N6Yv5rvn4GXP7 The sea otter is the only marine mammal on earth with no blubber at all. Between its body and near freezing water there is nothing but fur — up to a million hairs on a single square inch, the densest coat of any animal alive. That coat is also the reason the species was hunted down to less than one percent of its original numbers between 1741 and 1911. In this video: how the fur actually works, the leaky mitochondria that turn sea otter muscle into a furnace, the stone each otter carries in a pocket under its arm for years, and what happened to the kelp forests of the North Pacific once the otters were gone. 👍 Subscribe for new wildlife documentaries every week. #seaotter #seaotters #otter #wildlife #wildlifedocumentary #animalfacts #marinemammals #kelpforest #alaska #bigsur #natureducation #animalplanet #oceanlife #furtrade #keystonespecies
