What makes sharks and rays special? a. they are invertebrates b. they are the only fish with an exoskeleton c. their skeleton is made of cartilage. quick

It's strong and flexible and means they can turn quickly when chasing prey. A ray is essentially a flattened shark. They still have the same flexible skeleton, but it has been squashed and stretched and the pectoral fins have developed into “wings”. They both have unique skin that is covered in tiny modified teeth.
Most species of shark eat things like fish, crustaceans, mollusks, plankton, krill, marine mammals and other sharks. Sharks also have a very acute sense of smell that allows them to detect blood in the water from miles away.

Hopefully this helped hun! Have a good day !
