What part of a male shark is used for mating reproduction?
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.
How do sharks reproduce what is unique about the males?
Male sharks have paired reproductive organs called a claspers, and female sharks have an opening called a cloaca.

What causes mating scars on sharks?
Abstract. On rare occasions, during mating season among sharks, ‘mating scars’ appear on female sharks’ bodies caused by the males holding onto them. These scars are mostly deeper cuts and punctures, indicating a more forceful motivation such as coercive mating from the male’s side.
How does a male shark give birth to a female shark?
Sharks give birth to live young or fertilized eggs. In order for female sharks to give birth to live young or fertilized eggs, males must be able to deliver sperm internally to the female. The clasper, just like the penis, is another of evolution’s unique methods for this delivery. Shark claspers and pelvic fins.
Where are the reproductive organs located in a shark?
At the back of the pelvic fins are the male reproductive organs called claspers, which transfer the sperm to the female. Is common that the male bites the female shark to get its interest or to immobilize it. The mating usually consists of the insertion of the clasper within the oviduct.
How can you tell a male shark from a female shark?

What makes a shark different from other animals?
One of the main differences between sharks and other animals is that the males have claspers that they use to get the sperm into the females. Sharks have two claspers one on each side of their body.
How do Sharks reproduce sexually?
Depending on the species of shark, the process of reproduction could be sexual or asexual. With sexual reproduction there is the mating of a male and female shark that takes place. The male is able to deposit sperm into the female which will fertilize the eggs.
How often do Sharks reproduce?
It is also possible that the gestation period lasts from 3 to 4 months or up to more than two years. Large sharks often have a gestation period longer than the small species and reproduce every two years , while the little ones have offspring each year.
What are the reproductive organs of a shark?
All sharks practice internal fertilization. Male sharks have paired reproductive organs called a claspers, and female sharks have an opening called a cloaca. Fertilization occurs when a clasper is inserted into the cloaca and sperm is injected into the female.
How do sharks mate?
All sharks mate through internal fertilization. The male inserts one or both of his claspers into the female’s reproductive tract and deposits sperm. During this time, the male may use his teeth to hold on to the female, so many females have scars and wounds from mating.
