There are many fabulous pictures of Puffins with their bills full of dangling fish, many times all neatly lined up. Hmmm... how a Puffin can hold one fish while catching another? The answer lies in the spines on their tongues and roofs of their mouths, securing spearing a fish. Because of their way of holding the fish, scientists have been able to count up to 60 fish (albeit small ones) in a hungry Puffin's mouth.
