Correct Answer:
Male shark-Claspers borne on pelvic fins
Explanation:
A male shark possesses a pair of claspers which are inserted into a female shark’s cloaca (an opening on the underside of the body) at the time of mating. Claspers are located on the inner edge of the pelvic fins near the male’s cloaca. The function of claspers is to introduce sperm into a female shark’s body for the purpose of fertilizing her eggs. Female sharks do not have claspers.
