What is Sixgill shark?

Sixgill, known as its scientific name Hexanchus griseus , is a genus of shark, which consists of two separate species: Bluntose Sixgill Shark and Bigeye Sixgill Shark. His name is derived from the fact that he has six sets of gills. Most sharks have only five sets of gills. Also distinguishing both types of hexanchoid shark from other types of sharks has a unique dorsal fin, which rests near the tail of fish. Most sharks have two dorsal fin, rear dorsal fin and one closer to their head. Other common names for both species are a shark of the mud and cow shark.

Bluntosse Sixgill Shark is more common in both types and is sometimes hunted for play and commercial purposes. Usually it occurs in deep sea waters, up to 6 150 feet (1,875 meters) deep, but occasionally seen in the shallows. Its distribution is considered to be anywhere in the world with warm climate and is most often seen along the coast of Bay, Ca., South Africa and British Columbia. About the reproductive nature ofThere are not many swirling, but they give birth to live sharks, not eggs.

Shark toys can be up to 20, which is most likely to combat high mortality. Once it matures, it can reach a length of up to 16 feet (4.8 meters) and weigh more than £ 800 (362 kilograms). It is a long -term type of shark, with estimates indicating that it can live in the wild by 80 years. Bluntose Sixgill is unique among many sharks of its size because they hunt live prey; Usually smaller fish, rays and sea mammals. Many sharks of size survive on the diet of plankton.

Bigeye Sixgill Shark is less than Tuntos, usually about 5 feet (1.5 meters) and weigh around 40 pounds (18 kilograms). Almost exclusively occurs in deep waters, up to 1,970 feet (600 meters) deep, so very little is known about feeding or breeding sharks. It is assumed that they feed on small fish and small animals at the bottom. But there is evidence,They indicate that they sometimes rise to feeding shallow water fish, such as tuna and other small fish.

In addition to the size difference, it is very similar to the appearance of the Bluntoste shark. As its name suggests, it has larger eyes than most sharks of similar size. Neither Bluntnosis nor the Bigye Sixgill shark is of danger to humans.
