Modified scales resembling hairs on the underside of the feet of many gecko species, including the day gecko or crested gecko, also facilitate movement.

Do snakes have skin or scales?

What animals have scutes on their skin?

Reptiles with prominent scutes include crocodiles, alligators, and turtles. Scutes on alligators and crocodiles are the bony, ridged plates that make up the animal’s tough skin, protecting it from predators and possibly helping it regulate its temperature. These scutes have a bony base and are known as osteoderms.

Do crocodiles have scutes on their skin?

Crocodiles have scutes. Reptiles with prominent scutes include crocodiles, alligators, and turtles. Scutes on alligators and crocodiles are the bony, ridged plates that make up the animal’s tough skin, protecting it from predators and possibly helping it regulate its temperature.
