How do grey nurse shark have babies?

Answer 1

Mating occurs mainly in autumn and is followed by a 9 - 12 month gestation period and the young are born in winter. Towards the end of the gestation period, the more fully developed embryos eat the less developed embryos and unfertilised eggs within the female shark's uterus. As a result, only two pups are produced per litter - one in each uterus. Grey Nurse Sharks tend to breed only once every two years. This is the lowest reproductive rate of any shark and makes it more susceptible to external pressures that increase mortality.
