Do Crocodiles Have Gizzards?

It might not surprise you but other poultry have gizzards too, like turkeys, ducks, fowl, emus, doves, and pigeons. A little more surprising might be that crocodiles, alligators, earthworms, some fish and crustaceans, and even dinosaurs have gizzards.

What animals have gizzards?

The gizzard is very thick and muscular in some species, such as ducks, gallinaceous birds (those related to chickens such as grouse, quail, and turkeys), emus, and doves. Most of these birds eat hard items such as seeds and nuts. Birds with thick gizzards frequently pick up grit—little stones, sand, and small shells.

Do reptiles have gizzards?

Reptiles with Gizzards

With no grinding teeth with which to chew meat, the job of breaking down food falls to the reptile's gizzard. Just like birds and earthworms, they swallow stones to aid in this process. Crocodiles and alligators are the only reptiles, so far known to science, that have gizzards.
