What are the names of animals whose body is covered with horny scales?

Horny scales are found in many animal species. These are crocodiles, lizards and others. These animals are reptiles. But this is only a part of the animals that are characterized by horny scales. Reptiles are only part of the animals. Many organisms of the amniote group have scales. It is in the amniote that the scales are formed from horny scales. In fish, scales are formed by bony plates.
