The Incredible Diversity of Jawless and Cartilaginous Fish

Cartilaginous fish and jawless fish are quite different to bony fish. These two groups, also known as Chondrichthyes and Agnatha respectively, build their skeletons using cartilage.

A tough but flexible tissue, lighter than bone, that allows them to maintain neutral buoyancy without any need for a swim bladder.

In this video we'll take a look at the differences between jawless fish and cartilaginous fish, and discuss their adaptations and behaviours within the deep sea ecosystem.
