Sharks are a group of elasmobranch fish characterized by a cartilaginous 

skeleton, five to seven gill slits on the sides of the head, and pectoral fins 

that are not fused to the head. Modern sharks are classified within the clade 

Selachimorpha and are the sister group to the rays. Under this broader 

definition, the earliest known sharks date back to more than 420 million years 

ago. Acanthodians are often referred to as "spiny sharks", though they are not 

part of Chondrichthyes proper, they are a paraphyletic assemblage leading to 

cartilaginous fish as a whole.

Shark teeth are embedded in the gums rather than directly affixed to the jaw, and 

are constantly replaced throughout life. Multiple rows of replacement teeth grow 

in a groove on the inside of the jaw and steadily move forward in comparison to a 

conveyor belt. Some sharks lose 30,000 or more teeth in their lifetime.

Jaws of sharks, like those of rays and skates, are not attached to the cranium.
