In biology, a clasper is a male anatomical structure found in some groups of animals, used in mating. A close up view of a chimaera clasper (Hydrolagus collie). Note the many small tooth-like projections covering the exterior surface.

Apr 17, 2013 · Research has shown that the species reaches sexual maturity at age 15, and that males have a modified pelvic fin called a clasper to impregnate females (internally).

May 1, 2015 · Cartilaginous fishes, like sharks and rays, are blessed with something called “claspers,” dual sperm-releasing tubes jutting from their pelvic fins. Why two? Thanks to a recent study published...

Two Intromittent Organs: Male sharks possess two intromittent organs, known as claspers, located on the pelvic fins. These claspers function as specialized structures for transferring sperm to the female reproductive tract during copulation.

Technically, male sharks don't have penises. What they do have are grooved organs that are used to deposit sperm into the genital duct of sexually receptive female sharks. These organs, called 'claspers', are developed along the inner margin of each pelvic fin (the paired fins located behind a shark's belly).

Oct 14, 2022 · Great white sharks reproduce through the male inserting one of his two claspers (penises in the shape of a modified pelvic fin) into the female shark’s cloaca. The “process” for shark mating is somewhat similar to what most people are familiar with, although there are a few differences that are worth noting.

Dec 19, 2024 · White shark - Reproduction, Migration, Behavior: Reproduction in white sharks is viviparous. As top predators, they have few natural enemies except humans. Humans hunt and sell them commercially for many purposes. IUCN classifies white sharks as a vulnerable species.

In all extant male sharks, the pectoral fins sport paired, sausage-like intromittant organs called "claspers", which are used to transfer sperm into the body of receptive female sharks. The pectoral and pelvic fins correspond, respectively, to the arms and legs of humans.

HAROLD L. PRATTJR., in Great White Sharks, 1996. In the adult white shark, the claspers are scroll-shaped heavily calcified appendages that protrude 35–40 cm from the medial margin of the pelvic fin. They are robust structures, 5–7 cm in diameter (Fig. 1).

Apr 11, 2024 · Great White Sharks have a reproductive system known as internal fertilization. This means that the male shark will insert one of his two claspers (a modified pelvic fin) into the female's cloaca (a common opening for the reproductive, excretory, and digestive systems) to deposit his sperm.
