Do female sharks have two reproductive organs?
By latching on to the female’s fin, the male remains close enough for one of his two – yes two – reproductive organs (known as claspers) to deliver his contribution. And why the two “penises”? Unlike a true penis, a shark’s claspers aren’t an independent appendage.
How do female sharks reproduce?
In sharks, asexual reproduction can occur when a female’s egg is fertilised by an adjacent cell known as a polar body, Dudgeon says. “Mum’s genes get passed down from female to female until there are males available to mate with.”
Why do female sharks have scars from mating?
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.

What does sharks reproduce without mating?
In sharks, asexual reproduction usually happens via a process called “automictic parthenogenesis,” explained Feldheim. During egg development, one egg is produced along with three other products called polar bodies. Usually these polar bodies are simply reabsorbed by the female.
How do sharks mate and have babies?
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. When mating begins, a male shark will mount a female shark, either swimming beside or underneath.
Do sharks have AEX?
How often do sharks have sex? As often as possible. Unlike swans, who mate for life, shark sex “happens when it happens,” Burgess says. “It’s like 1 o’clock in the morning, and the bar’s closing.” Male sharks can sniff out ovulating females, who give off pheromones (chemical signals) when they’re ready for mating.
