TWO: Chondricythes- Possessing Cartilage, Heterocercal Ffin
Osteichthyes- Possessing Bones and homocercal fin.
fish are are vertebrates
Fish are general classified into one phylum which is known as chordata. There some fish like the hagfish that are not able to fit into this phyla properly.
My reference is a book which is "A Cyber Science".It says here that there are so many phyla.Example of phyla:Phylum PlatyhelminthesPhylum NemathelminthesPhylum AnnelidaPhylum ArthropodaPhylum PoriferaPhylum ChordataPhylum NematodaPhylum CoelenterataPhylum MolluscaPhylum GastropodaI can't explain these phyla but maybe a week, I can see a reference book who has these definitions.

There are 3 syllables. Bon-y fish.
The Osteichthyes is evolved from lungs of early bony fish. The fish have many types of evolved.
Bony fish belong to the Class Sarcopterygii (if lobe-finned) and the Class Actinopterygii (if ray-finned). Coelacanths and lungfish are lobefinned and about all other bony fish are ray-finned. The two classes used to be combined as Class Osteichthyes. There are many superorders and orders in the bony fish classes.
Bony fish have many gill filaments because they use them to breathe. They are also used to transfer things like water and ions.
There are seven classes of vertebrates. They are the jawless fish, the cartilaginous fish, the bony fish, the amphibians, the reptiles, the mammals, and the birds. Within each group there are many species.

3 types of fish. Cartilage, Boney, and Jawless.
The vertebrate of a fish is made up of three bony elements made up of other tiny bones. The number of bones actually depends on the type of fish.
