Sharks are a diverse group of marine predators that exhibit a variety of unique characteristics. They are members of the Chondrichthyes class, and unlike vertebrates like mammals and birds that have bones for structural support, how many bones do sharks have have a cartilage skeleton? This makes them a unique member of the fish kingdom and allows them to move faster and more precisely through the water than their skeleton-bearing counterparts.
Shark skeletons are composed of a flexible connective tissue called cartilage, which is lighter and more pliable than bone and capable of sustaining muscle and skin in place. Cartilage is similar to the squishy layer found in your ears and nose, but it’s far more durable than bone and can withstand a significant amount of physical stress.

In addition to being able to endure immense amounts of pressure, shark cartilage also heals much more quickly than bones. This is particularly helpful for sharks, as their skeletons are susceptible to serious injuries in the event that they are bumped or struck by prey.
Although sharks lack bones, their skeletal system still functions just as effectively. The light, supple structure of cartilage helps them to conserve energy while moving swiftly through the water, and their ability to heal more rapidly means they can return to hunting and feeding more quickly after any injuries. This is why it’s so easy to spot a wounded shark in the water – its damaged skeleton can often be clearly seen.
