Shark Trivia

Did You Know that some Sharks have multiple Dads….

.….through what is known as multiple paternity and a single litter of shark pups can have anywhere from one to five dads based on DNA samples taken from litters of shark pups? Multiple paternity is thought to be more common in shark species whose females can store sperm after mating for later use and in species that gather together at breeding time, which increases the number of available mates.

Multiple paternity appears to be very common among sharks and has been documented in several species including in Bonnethead Sharks, Lemon Sharks, Leopard Sharks, Nurse Sharks, Sandbar Sharks, and Small-Spotted Catsharks.

Females may even be forced to mate with more than one male even if they do not need to do so to impregnate, resulting in litters with more than one dad. Advantages though also include increased genetic diversity within a litter and increasing mating opportunities for males.
