They’re ambush predators, using wormlike appendage on tongue to attract prey.

They lay anything from 8-52 eggs in a clutch.

More active at night (nocturnal).

Fun Fact(s):
They can stay submerged for up to 50 minutes-actually less than many other turtle species.

While these turtles not as aggressive as common snappers, they can do more damage w/ their sharp hooked beaks & stronger bite force.

Due to appearance, sometimes called “dinosaurs of the turtle world.”

They get their name from their appearance.
