What are the kind of finfishes?

Finfishes, also known as bony fishes, are characterized by a skeleton made of bone rather than cartilage. They belong to the class Osteichthyes and include diverse species such as salmon, tuna, goldfish, and cod. Finfishes are typically divided into three main groups: ray-finned fishes (Actinopterygii), lobe-finned fishes (Sarcopterygii), and the extinct group of crossopterygians. They inhabit various aquatic environments, from freshwater rivers to the deep sea.
