Mitsukurina owstoni is found in the deep ocean, far below where the sun's light can reach at depths greater than 200 meters. They can be found throughout the world, from Australia in the Pacific Ocean[3] to the Gulf of Mexico in the Atlantic Ocean.[4] They are best known from the waters around Japan, where the species was first discovered by modern science.[5]
Goblin sharks feed on a variety of organisms that live in the deep waters they call their home. Among some of their known meals are deep-sea squid, crabs and deep-sea fishes. Very little is known about the species' life history and reproductive habits, as encounters with them have been relatively rare. As seemingly rare as they are however, there seems to be no real threat to their populations and so they are not
