Goblin Shark Catch, Green Cape, New South Wales, Australia, South Pacific Ocean

• Life history
Little is known about goblin shark reproduction because a pregnant female has yet to be found and studied. It likely shares the reproductive characteristics of other mackerel sharks, which are viviparous with small litter sizes and embryos that grow during gestation by eating undeveloped eggs (oophagy). The birth size is probably close to 82 cm (32 in), the length of the smallest known specimen. Males mature sexually at about 2.6 m (8.5 ft) long, while female maturation size is unknown. No data are available on growth and aging.
