Product Information

There has been no direct study of goblin sharks in the wild, so there is no information on there mating habits. Asexual: Though a very rare form of breeding that has only been observed in captivity with a Hammerhead shark, female sharks are able to reproduce without a mate. The gestation period for ovoviviparous sharks varies greatly depending on the species. It can range from a few months to over a year.

Sharks come in over 500 different species with a wide range of habits. They lay eggs in three main ways: oviparity, viviparity, and ovoviviparity. Some examples of sharks that exhibit placental viviparity include hammerhead sharks and blue sharks. Uterine OophagyDuffy, C. 1997. Futher Records of the Goblin Shark, Mitsukurina owstoni (Lamniformes: Mitsukurinidae), from New Zealand. New Zealand Journal of Zoology, 24: 167-171. In rare cases, it is also seen that when the female doesn’t get any potential male to mate with her then they can also reproduce asexually. This is the third in our series of 'I want to know about...' blogs. This one will cover the topic of shark reproduction. Instead, the embryos receive nutrients from the egg yolk. The pups hatch inside the mother’s body and are born alive.

Now, the majority of sharks are known as ovoviviparous. It is similar to viviparity, however there are a few key differences. You may sometimes see it referred to as aplacental viviparity. This is because there is no placenta present in this method. However, the mother's body does provide gas exchange (respiration).Tens of millions of sharks are killed each year and many populations continue to decline at an alarming rate.

Viviparity is the most advanced method of reproduction. The baby shark develops inside their mother’s body, receiving nutrients and oxygen through an umbilical cord. This is the same method used by mammals. But, unlike mammals, when the pups are born they're immediately independent and have to fend for themselves. Using their eyes they know how and where to grab and copulate their partner with some foreplay actions.Ovoviviparity is a reproductive strategy used by some shark species. Instead of laying eggs, the female carries the embryos inside her body until they are ready to hatch. Each type has its own characteristics and adaptations that allow sharks to survive and thrive in their respective environments. Viviparity Sharks have many nerve endings under their skin and so they can experience distant touch through their lateral line and ventral body surface. They receive the nutrients and oxygen from an umbilical cord attached to the mother, much like mammals. The young will then live off the placenta until birth.
