Similar to a penis, claspers are an external appendage found on male sharks, skates, and rays that are designed to deliver sperm inside of a female. However, they are dissimilar to a penis in that they are not an independent appendage, but rather a deeply grooved cartilaginous extension of the sharks pelvic fins..
Consequently, how do shark Claspers work?
Male cartilaginous fish have claspers formed from the posterior portion of their pelvic fin which serve as intromittent organs used to channel semen into the female's cloaca during mating. The clasper is then inserted into the cloaca, where it opens like an umbrella to anchor its position.
Also, what are pelvic Claspers? Claspers are associated with ventral (pelvic) fins located near the cloaca and are used for transferring sperm to the female genital tract. In sharks, claspers are not used to grasp the female during mating as the name implies, but rather males grasp the females with their teeth during copulation.
Correspondingly, why do sharks have 2 Claspers?
These organs, called 'claspers', are developed along the inner margin of each pelvic fin (the paired fins located behind a shark's belly). Because the pelvic fins are paired, so are the claspers. That's really all there is to it. Curiously, although male sharks have two claspers, they only use one at a time.
How do you know if a shark is male or female?
Male sharks tend to be smaller than females. But the easiest way to tell them apart is to look for claspers. Males have a pair of claspers, which are used for mating. This is like a pair of extra roll-up fins under their body.
