When raising a chick in their burrows, Atlantic puffins must often fly miles out to sea to find food. Foraging trips burn energy, so they want to maximize the amount of food they bring back. In order to stuff as many fish in their beaks at once they have several clever adaptations. The flexible hinge of their jaw allows it to open much wider than on many other birds. The underside of their upper jaw is lined with back-facing spines (called denticles). Using their rigid tongue (pictured), they’re able to pin their prey against these spines. This allows them to continue to hunt more fish while holding on to the ones they’ve already caught!
