Sharp-toothed cannibal fish startle the beach visitors

The visitors of Jennette's Pier in Nags Head, North Carolina, United States last week made an absurdly surprised when the terrible fanged fish stranded alive on the beach.

The fish was identified as a long snout lancetfish (Alepisaurus ferox), noktunal predators fish - sleep during the day and are active at night - which is rarely seen on the beach. Fish is not only known for their large fangs and a long dorsal fin, but also because they eat their own species or cannibals.

Lancetfish found in North Carolina was alive when stranded on the beach, but when inserted into deeper water, he re-stranded. "That indicates that he might be ill," according to Nature World News, as quoted from LiveScience on Tuesday, May 20, 2014.

Because it is relatively rare lancetfish that inhabit the open sea, little is known about its life cycle. In adolescence, the hermaphrodite fish - having both male and female sex organs at the same time - although there is no evidence of when the adult hermaphrodite.

Lancetfish also known as handsaw fish, because their dorsal fins are long and jagged. The fish do not have scales, skin pores filled. Their scientific name, Alepisaurus, translated as "not scaly lizard".

Lancetfish body can reach a length of 2 meters. These fish usually feed at night. In addition to prey on one another, they also eat the animals crustaceans, squid, or other small fish.

Instead, lancetfish predation by seals, sharks, and other large fish, including tuna. The fish was not considered good fish for human consumption, because the muscles they contain a lot of water, making the meat mushy.

The fishermen consider lancetfish as 'garbage', and making valuable bait for fish such as tuna. Facts is their muscles contain a lot of water, making lancetfish can move quickly, pursue other prey, so scientists speculate that the fish are ambush predators.

Lancetfish often found in open waters throughout tropical and subtropical oceans, and often make long trips to Greenland and Iceland. *** [EKA | FROM VARIOUS SOURCES | LIVESCIENCE]
