Answers
Explanation:
In biology, a clasper is a male anatomical structure found in some groups of animals, used in mating.

Male cartilaginous fish have claspers formed from the posterior portion of their pelvic finwhich serve as intromittent organs used to channel semen into the female's cloacaduring mating. The act of mating in some fish including sharks usually includes one of the claspers raised to allow water into the siphon through a specific orifice. The clasper is then inserted into the cloaca, where it opens like an umbrella to anchor its position. The siphon then begins to contract, expelling water and sperm.[1][2] Male chimaeras have cephalic claspers (tenacula) on their heads, which are thought to aid in holding the female during mating.
Answer:
Claspers are organs that found on male elasmobranchs (sharks, skates, and rays) and Holocephalans (chimaeras). These parts of the animal are vital for the reproduction process.
