SEXUAL DIMORPHISM

Female sharks are larger than males.

Males have claspers, which are elongated pelvic fin edges. Claspers are used in reproduction. Females have a cloaca, one opening that serves digestive and reproductive functions.

Some scientists believe that when a male great white shark reaches a certain large size, it turns into a female.
