What is the class classification of a fish?
Fishes are typically divided into three groups: superclass Agnatha (jawless fishes), class Chondrichthyes (cartilaginous fishes), and superclass Osteichthyes (bony fishes).
What are the two classes of fish?
Fishes are divided into two main classes: chondrichthyes, fishes with cartilaginous skeletons (sharks, rays, dog-fishes), and osteichthyes, bony fishes (tuna, sardines, salmons).

What are the classes of fish and describe each?
Fishes are typically divided into three groups: superclass Agnatha (jawless fishes), class Chondrichthyes (cartilaginous fishes), and superclass Osteichthyes (bony fishes). The latter two groups are included within the infraphylum Gnathostomata, a category containing all jawed vertebrates.
What is the difference between the fish classes?
Cartilaginous fishes have skeletons composed mostly of cartilage while bony fish have a skeleton composed mostly of bone. Furthermore, these two types of fish fall under different taxonomic groups – Cartilaginous fish are grouped under the class Chondrichthyes and all bony fish fall under the superclass Osteichthyes.

What are the three classes of fish?
Scientists use these differences to put fish into three classes, or groups, by looking at their skeletons and the structure of their mouths. These three groups are the Superclass Agnatha, the chondrichthyes, and the osteichthyes. The first group of fish is the Superclass Agnatha. These are very primitive fish.
How many species of fish are there?
