Fishes with cartilaginous skeletons and no scales include members of the class Chondrichthyes, such as sharks and rays. These fishes have a skeleton made of cartilage instead of bone and typically possess smooth skin that lacks scales, although some may have structures called dermal denticles that provide a scale-like texture. Examples include the hammerhead shark and the manta ray.
