Instead of true vertebrae, they have a series of cartilaginous structures called arcualia arranged above the notochord.
Because cartilaginous fish do not have bone marrow, the spleen and special tissue around the gonads produces red blood cells.
Cartilaginous intra-articular bodies float freely within the synovial fluid, which they require for nutrition and growth.
However, their use is restricted largely to tongue and pharyngeal-wall function, given that most of the alimentary canal is shielded by bony or cartilaginous structure impervious to ultrasound waves.
The leaves are obovate and stalkless, with a cartilaginous edge, all growing in a basal rosette.
Lampreys and sharks only possess a cartilaginous endocranium, with both the upper and lower jaws being separate elements.
The skeleton, which forms the support structure inside the fish, is either made of cartilage, in cartilaginous fish, or bone in bony fish.
However, the exoccipital-opisthotic is fully formed, with no indication of a substantial cartilaginous component.
