The claspers of a wobbegong shark (Orectolobus maculatus).

In biology, a clasper or valva (plural valvae) is a body part of male insects that is used to hold the female during copulation.

Male cartilaginous fish also have claspers, which developed from their pelvic fins. These are intromittent organs, used to channel semen into the female's cloaca during copulation.
