The cartilage of a shark's skeleton may be important in future cancer research. To minimise heat loss mackerel sharks have a network of tiny capillaries which act as a heat exchange system (known as a rete mirabile). Found in an assortment of marine habitats, the creatures filter tiny food particles out of the water.

Brachiopods are ocean-dwelling animals that superficially resemble clams. WebIn elasmobranchs (sharks and rays), the job of manufacturing red blood cells is performed by the spleen, special tissue around the gonads (reproductive organs), and in at least some species by a special structure called "Leydig's Organ" (named after the German histologist who first described it in 1857). White muscle is used when the shark is either attacking or dodging predators, because it gives them an extra burst of quick energy and movement. A lot of heat is lost through a sharks gills, where blood vessels are exposed to cooler water.
