Holding the title for 'fattest animal in the world' , the Bowhead whale has up to 50 tons of blubber helping to keep it warm at home in the Arctic. It is also known as the "Arctic whale" or "Greenland right whale".
Some studies have suggested the Bowhead whale can live up to 200 years! They are quite possibly the oldest living mammal on earth...and they also have the largest mouth of any animal!
