How do puffins hold so much in their moouth?

Puffins have a unique adaptation that allows them to hold multiple fish in their beaks simultaneously. Their tongue is highly flexible and acts as a sort of "paddle," helping to secure the fish while they catch more. Additionally, the structure of their beak includes grooves that keep the fish in place without requiring a tight grip, enabling them to transport several fish at once back to their nests. This efficient method helps puffins feed their young effectively.
