SHARK REPRODUCTION

Unlike most bony fish, shark's eggs are fertilized inside the female's body. The male shark has "claspers," extensions of the pelvic fins that are used to transfer sperm to the female and fertilize her eggs.

Baby sharks (called pups) are born with a full set of teeth and are fully ready to take care of themselves. They quickly swim away, even from their mothers who might eat them. Litter size ranges from one or two pups (for a great white shark) to over 100 (for a large blue shark and the whale shark).
