The Bowhead whale, also called Arctic or Greenland whale. 🐋 Video by @taichi_maruyama Bowheads are the only baleen whales that spend their entire lives in the Arctic seas. They are among the longest-living mammals on earth, reaching over 200 years of age! Thanks to their layers of fat over half a meter thick and a forehead so powerful that they can pierce up to two feet of ice sheets to breathe, they have conquered some of the harshest conditions in the world. 🐳❄
