Cartilaginous Fish (Elasmobranchs)

Duration: 1.5 hours

Sharks, skates, and rays are separated from their vertebrate cousins into the class Chondrichthyes - the "cartilaginous fishes." With this course, you will learn the main differences between sharks and rays (cartilaginous fish), their key features and general concepts about cartilaginous fish biology.
