They have cartilage instead of bones for a skeleton. Chondo- means cartilage.
Elasmobranch is a class of fishes with bones made of cartilage. It includes sharks, skates and rays. Cartilage is the material that is in your nose and ears. Their only real bones are teeth and jaws. They are a very old, successful class of fishes. There were sharks before there were dinosaurs. Because they lack bones, there are very few fossils of older sharks. Sharks are endangered now because their cartilaginous fins are prized for soup in some cultures.
Mostly because they have more bones than other fish, making them stonger which means they are able to adapt more easily to environments then the fish with less bones :)
