The claspers of a spotted wobbegong shark (Orectolobus maculatus) The claspers of a young spinner shark (Carcharhinus brevipinna) 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 ...
Depiction of shark anatomy including eggs, pups, and the liver. Sharks' reproductive organs serve to reproduce sexually where the male delivers sperm to the female using claspers that insert into the female's oviduct. This then allows the female to give birth to live young, although some do lay eggs.
In male members of Chondrichthyes (sharks and rays), as well as now-extinct placoderms, the pelvic fins bear specialized claspers. During copulation, one clasper is inserted into the female's cloaca, and sperm is flushed by the male's body through a groove into the female. [7] Members of Poeciliidae are small fishes that give birth to live young.

The posterior part of a male shark's pelvic fins are modified into a pair of intromittent organs called claspers, analogous to a mammalian penis, of which one is used to deliver sperm into the female. [75] Mating has rarely been observed in sharks. [76] The smaller catsharks often mate with the male
After a period of synchronous swimming, the male pushes the female on her side and positions her so her head is against the bottom and her tail is raised. Once the female is in position, the male inserts one of his claspers into her cloaca. Copulation lasts for several minutes, after which the sharks separate and resume their regular behavior. [34]
A female shark has hatched an egg without it being fertilised by a male, a zoo in Illinois has said. Brookfield Zoo said the hatching of an epaulette shark pup was not unusual, but the way in ...
Mating in the epaulette shark takes place from July to December, though in captivity reproduction occurs continuously. [1] [21] Courtship may be initiated by the female following and biting the male. The male then holds onto the pectoral fin of the female with his mouth and lies alongside her, while inserting one of his claspers into her cloaca.
