Centrophorus Harrissoni – Dumb Gulper Shark
The Dumb Gulper Shark, sometimes called the Dogfish Endevour or Harrison’s Dogfish, is an endangered species of shark that is found off the east coast of Australia and around Tasmania and New Zealand. They can live up to 46 years on average and can reach up to 110cm in length.
Like other Gulper Sharks, they live in deep water and are usually found at depths between 250 to 385 meters under the surface. Their large green eyes, a feature of all members of the genus Centrophorus, help them see through the murky waters of the deep ocean. Their diet mostly consists of fish as well as cephalopods, like squid, and crustaceans.
They are categorized as endangered because there has been a decrease of up to 99% in population levels in some areas since the 1970s. Like other gulper sharks, they are unable to rapidly recover their threatened populations because they have long gestation periods and low birth rates. They usually only produce one or two pups every couple of years.
