Catch an extremely rare 'alien' shark

Fishermen have caught a megamouth shark at the coast of Japan. This is the 58th child ever found in the world.

This wide-mouth shark has caught Japanese fishermen last month. Later, it was put on display at the Marine Science Museum in Shizuoka City. This is a female with a weight of nearly 1.5 tons and a length of 4m. The Japan Daily Press daily reported on May 8 that museum scientists performed an autopsy on the animal.

The mouth shark is 1.5 tons wide, caught by Japanese fishermen

The wide-mouth shark is dubbed the 'alien shark' by its peculiar head. This is considered one of the most rare fish species in the world, only discovered in some waters such as California, Japan, Taiwan, Indonesia, Brazil, Ecuador, Senegal, South Africa, Mexico and Australia . According to the Florida Museum of Natural History, wide-mouth sharks often live in the Indian Ocean, Pacific Ocean and Atlantic Ocean.

These sharks are like whale sharks and basking sharks, which are widely distributed. However, it is less active and less capable of swimming than the other two species. In the daytime, it was in deep water, only until the night came up near the water to hunt. Their food is mainly plankton, mollusc.

Only 58 wide mouth sharks are found by humans

Since it was first discovered in 1976, only 58 wide mouth sharks have been found so far. In 2009, Sorsogon fishermen in the Philippines unknowingly caught a wide mouth shark but then they sawn and eaten it.
