What is a shark?
Goblin shark is a type of shark deep water that has a retractable jaw. Rarely visible, goblin sharks are not studied in large numbers, but are considered relatively common. The scientific name for the Goblin shark is Mitskurina Owstoni . His tail is asymmetric, much longer above than it is at the bottom. The largest of this species when 12.6 feet (3.8 m) was recorded, but an average of about 5 feet (1.6 m). Of the several samples studied, women seem to be larger than men.
The most remarkable feature of this shark is its jaws. The connection with the mandibular joints of the ligaments that are either relaxed or repaired are the jaws are able to shoot forward to capture the prey. When the bonds are repaired, the jaws sit against the body, their crescent shape seems to be very similar to the other more known types of sharks. When the meaning of the Goblins sharks, the ligaments relax and the jaws flash quickly, the mouth wide to capture the prey in freely placed teeth of similar needles.
Goblin shark senses potential food using organs in its muzzle called ampullae, which they use to detect bioelectric signatures of their prey. Probably remains mostly motionless when hunting, which prefers prey to her. Goblin sharks eat shrimp, octopus and soft fish and crabs. Their diet is unknown because there are few scientific information about their stomach content.
are most often found in Japan, goblin sharks live on external continental shelves around the world. After being found at depths of 130-3 940 feet (40-1 200 m), they are assumed that they live near the bottom or on the middle level of their ocean habitats. It is assumed that they are slow swimmers because their asymmetric tails and muscle tone are not suitable for speed.
Because a pregnant woman has never been caught, reproduction means are not known. However, scientists speculate that these sharks are Ovoviviparous, which means they give birth to live offspring, but the offspring are incubated inside the fertilizer eggs that hatch inside the body before birth. Scientists have come to this conclusion, because most other sharks of the Lamniformes - which include goblin sharks - is Ovoviviparous.
Goblin shark is rarely intentionally caught and is usually a secondary commercial fisherman. It is assumed that there is a minimal danger to humans, but had relatively small contact with people. There are about 45 specimens of the Goblin shark for the study of scientists.
