[edit] Taxonomic classes of fish
Modern fish (those that are not extinct) are found within two superclasses of the phylum Chordata. The superclasses are Agnatha the jawless vertebrates, and Gnathostomata (vertebrates with jaws). Within these superclasses there are four classes and two subclasses:
- Superclass Agnatha Vertebrates without jaws, a paraphyletic superclass containing:
- Class Myxini - hagfish
- Class Cephalaspidomorphi - lampreys
- Superclass Gnathostomata Vertebrates with jaws
- Class Chondrichthyes (cartilagineous fish - sharks and rays)
- Class Osteichthyes (bony fish), which has two subclasses:
- Actinopterygii (ray-finned fish)
- Sarcopterygii (lobe-finned fish)
- Full details of higher order fish taxonomy can be found in the Chordata article.
