How do sharks reproduce?<\/h2>\n

Sharks reproduce by internal fertilization, which means they mate. Once the eggs have been fertilized, they develop in different ways depending on the species.<\/p>\n

    \n
  1. Oviparous species lay their eggs in water or in crevices, where they develop until they hatch.<\/li>\n
  2. In viviparous species, the embryo develops inside the mother\u2019s uterus.<\/li>\n
  3. Most species are ovoviviparous, meaning that eggs develop and hatch inside the mother.<\/li>\n<\/ol>\n

    Gestation periods vary from species to species. Generally, they are very long periods, up to 2 years in a Dogfish. Unlike most bony fish, sharks have very few offspring\u2014sometimes only one. where a few, in some cases one, offspring are produced. After birth, it takes a long time for a shark to reach maturity. It can take Nurse Sharks 15\u201320 years before it is ready to reproduce.<\/p>\n","protected":false},"excerpt":{"rendered":"
