Kingdom: Animalia (Animals)

Phylum: Chordata (notochord)

Subphylum: Vertebrata (animals with back bones)

Then, there are three major classes.

  • Agnatha (jawless fish such as the hagfish and lampreys)
  • Chrondrichthyes (fish whose skeleton is made of cartilage such as sharks, rays and skates)
  • Osteichthyes (bony fish; skeleton is composed mostly of bone such as bass, perch, catfish, and flounder)

The majority of fish belong to the osteichtyes. The study of fish is call ichtyology.
