Chondrichthyes are fish that have bones made of cartridge rather than bones. They also have multichambered hearts, fins in pairs and jaws. Sharks of different kinds fall into this category.
They have cartilage instead of bones for a skeleton. Chondo- means cartilage.

The main difference between Agnathans (jawless fish) and Chondrichthyes (cartilaginous fish) is the presence of jaws. Agnathans lack jaws, while Chondrichthyes have well-developed jaws. Additionally, Agnathans have a cartilaginous skeleton, while Chondrichthyes have a skeleton made of cartilage.
