- Jawless Fishes-have no jaw, but a roundmouth, a tube like body made of cartilage (flexible, like your nose), no scales; have slimy skin. Examples: lamprey and hagfish (google them).
- Cartilaginous Fishes-skeleton made of cartilage, movable jaws, have scales. Examples: sharks, skates and rays.
- Bony Fishes-skeleton made of bone, 95% of all fish species, covered by bony scales, have a swim bladder (helps fish keep balance), reproduce by external fertilization called spawning; some species have internal fertilization. Examples: perch, bass, northern pike, salmon, and goldfish.
