Osteichthyes

Diverse clade of vertebrate animals

Osteichthyes

Summary

Osteichthyes, also known as osteichthyans or commonly referred to as the bony fish, is a diverse clade of vertebrate animals that have endoskeletons primarily composed of bone tissue, encompassing both the conventional bony fishes and, in a cladistic sense, all tetrapods. They can be contrasted with the Chondrichthyes and the extinct placoderms and acanthodians, which have endoskeletons primarily composed of cartilage. The vast majority of extant fish are members of Osteichthyes, being an extremely diverse and abundant group consisting of 45 orders, over 435 families and 28,000 species.

"scleral" is a better word than "sclerotic" (see discussion [[Scleral_ring#Terminology|here]]
