Is the starfish classified as a amphibian?

The starfish is classified as a member of the family Leastreidae. The classification of Leastreidae is an extinct family whose members lived from the Cretaceous period to the Triassic. Most species are found in coastal regions of the Atlantic and Pacific oceans.

These species are not found in many places where other types of fish such as snappers and swordfish would be found or in areas that are not conducive to fish growth due to low levels of carbon dioxide.

One of the largest member families to live in the deep sea are the Gomphodontidae, which include only 20 species. These fish have shells made from keratin and are usually found off the Atlantic and Pacific coasts of the United States.
