How is a fish different from a reptile?

The main differences between fish and reptiles are:fish breathe through gills and reptiles breathe through lungsFish have scales and reptiles have scaly skinFish must live in water but reptiles are terrestrial (except for turtles)


Are fish classified as reptiles?

No. Fish are one of the five families of vertebrates (animals with backbones) that include fish, reptiles, amphibians, birds and mammals. Fish are similar to reptiles being cold blooded, they lay eggs, and have scales, but are different from reptiles as fish breathe through gills and live exclusively underwater, whereas reptiles breathe through lungs on land. Fish lay eggs that have thin membranes (skins) in water. Reptiles usually lay eggs with thick leathery skins on land.------------------------------------------------------------------------------------------BUT,fish pretty much evoled to make reptiles.so if you look at it,reptiles are like land living fish!both have scales and most lay eggs... a FISH is definitely NOT A REPTILE.... fish are in the family of fishes. and although they seem like a reptile with teeth, scales and dinosaur-like, they are completely different from reptiles like their insides, fins and skills. hope my answer helped! :)


Does reptile have scales?

Yes, reptiles have scales that provide protection and help regulate body temperature. The scales are made of keratin, the same material that makes up human hair and nails.


What is the body covering of a reptiles?

Reptile skin is covered with scutes or scales which, along with many other characteristics, distinguish reptiles from animals of other classes (except fish). Scales are made of keratin and are formed from the epidermis . They may be ossified or tubercular, as in the case of lizards, or modified elaborately, as in the case of snakes.


What is the name of a reptile with a hard protective shell?

Reptiles have a body covering of dry, scaly skin. They do not have individual scales as fish do, but the scales (also known as scutes) are joined together to form a seamless outer covering of skin. The scales are made of keratin, the same substance of which human fingernails and hair are made.
