What is a shark cow?

The most primitive of all types of sharks are sharks of cows scientifically known as hexanchidae. This family of fish consists of four separate species. They are characterized by very simple digestive and excretory systems, preferences of mostly warm, deep seas and other pairs of slits. While most sharks have five pairs of slits, these sharks have either six or seven.

skeletons of cow sharks are very simple and resemble structures of a body of similar but extinct animals. Unlike many other types of sharks, hexanchidae has very little adaptation to the modern world. Their excretion and digestive systems are not specialized as most contemporary species, which also means a relationship to primitive species.

Gray or brown upper part is listed on most sharks. Their underbaths are usually a slightly lighter shade. Animals also have a hard body, one dorsal fin and the only anal fins, as well as sharp, thorn teeth. The ENGILL Cow Sevžraloci are also known as the Sea Wolves.

Hexanchidae can range from almost five feet (one and half meters) to 18 feet (five and half meters) to length. Ovoviviparous Fish, women of shark cow sharks carry eggs until they hatch. The cow's shark diet ranges from crustaceans and carrots to all different fish species, including different types of sharks.

Four independent species form a family of sharks of cows. Heptranchias, or Sharpnose Sevengill Shark, has seven gills, as well as the genera Notorynchus or Broadnos Sevengill Shark. The first is a small but aggressive fish found in deep water in tropical and mild zones. It can be very large, up to 10 feet (300 centimeters) in length and is known to attack people.

The

family hexanchus, which has six gills, consists of two types: Bluntnosis and Bigeye Sixgill Sharks. Unlike TON, two more species, these two sharks are less aggressive and it was not known to attack people. Both givePriority of deep waters that measure at least 300 feet (90 meters) to depth or more.

ranges of habitat for sharks of cows are very wide. Fish live in the Atlantic, Pacific and Indian Oceans. They can usually be seen in the waters of the slope and also in the continental shelf. Fish prefer muddy, sand waters and rocky areas. In South Africa, the False Bay sharks, the sea protected area, occupy. No additional nature projects are used to protect the shark cows.

Sometimes he embarks on the shallow coastal waters where people see them. People should avoid contact with sharks because some species are attacking. The shark of cows is commercially hunted in some areas, including the United States, China and Australia. It is used as a source of food and its skin, which is sold as a leather product.
