1. Osteichthyes

   Osteichthyes (), popularly referred to as the bony fish, is a diverse superclass of vertebrates, that have skeletons primarily composed of bone tissue. They can be contrasted with the Chondrichthyes, which have skeletons primarily composed of cartilage. The vast majority of fish are members of Osteichthyes, which is an extremely diverse and abundant group consisting of 45 orders, and over 435 families and 28,000 species. It is the largest class of vertebrates in existence today. The group Osteichthyes is divided into the ray-finned fish (Actinopterygii) and lobe-finned fish (Sarcopterygii). The oldest known fossils of bony fish are about 425 million years old, which are also transitional fossils, showing a tooth pattern that is in between the tooth rows of sharks and bony fishes.Osteichthyes can be compared to Euteleostomi. In paleontology the terms are synonymous. In ichthyology the difference is that Euteleostomi presents a cladistic view which includes the terrestrial tetrapods that evolved from lobe-finned fish. Until recently, the view of most ichthyologists has been that Osteichthyes were paraphyletic and include only fishes. However, since 2013 widely cited ichthyology papers have been published with phylogenetic trees that treat the Osteichthyes as a clade including tetrapods.

1. osteichthyes

   Osteichthyes is a taxonomic group of fish, also known as bony fish, which are characterized by a skeleton made of bone rather than cartilage. They are the largest class of vertebrates in terms of species count, and include a vast diversity of fish found in nearly all aquatic environments. The group is divided into two subclasses: ray-finned fish (Actinopterygii) and lobe-finned fish (Sarcopterygii). Osteichthyes are also distinguished by their gill structure and the presence of an operculum, or gill cover.
