The goblin shark, Mitsukurina owstoni, is found in the deep ocean, far below where the sun's light can reach at depths greater than 200m and is the sole living species in the family Mitsukurinidae.
The Greenland shark (Somniosus microcephalus) can grow to more than 7 metres, which makes it even larger in lenght than the Great White. It lives in the polar waters of the Atlantic Ocean, though it also appears more to the south. It's teeth are small but razor sharp. In fact, in the past the Inuit used it for cutting off hair. The Greenland shark is closely related to the Pacific sleeper shark (sominosus pacificus).
Australian Ghost Shark lives at depths of 200 to 500 meters and grows to between 60 and 120 centimeters. The shark mates in the spring and females lay eggs contained in large capsules on sandy or muddy substrate.
This shiny silvery colored fish has a snout with a fleshy hoe shaped appendage that is used to forage for food in the muddy ocean floor, using sensory canals and the pores on its head. Its large serrated spine is though to be poisonous, but there have been no reports of serious injury.
The slow growth of this shark, along with its limited range makes this species vulnerable to intensive fishing by commercial trawlers due to their popularity in fish and chips restaurants in New Zealand and Australia.
