In [[biology]], a '''clasper''' or '''valva''' (plural ''valvae'') is a body part of certain male animals, used in mating.
In [[entomology]], it is a structure in male insects that is used to hold the female during [[copulation]].
Male [[cartilaginous fish]] also have claspers. These are [[intromittent organ]]s, used to channel semen into the female's [[cloaca]] during copulation.
