Because Japanese spider crabs are dull and easy to catch, catching giant spider crabs has become an important branch of aquaculture. In order to protect this species, Japan has issued a ban on fishing during the spawning period of giant spider crabs.

In some film and television works, there is a huge, man-eating crab, commonly known as "man-eating crab" Is there really such a crab in the sea?

In the southeast coast of Japan, there is a spidery spider crab. When it grows up, it is huge, and its sharp claws are more than 3 meters long. It lives in the deep sea floor of more than 3,600 meters, and only in the breeding season will it climb to the shallow sea to lay eggs. The pincers of this crab will bind people and eat them when they are exhausted. This crab should be a man-eating crab.

Spider crab's body is spindle-shaped, with sharp ends and a long, spiny back like a hard shield. Coupled with sharp legs, 10 crab claws are long and sharp, and a pair of claws are hard and powerful, which makes people feel creepy. This deep-sea troll, with all its claws stretched out, can reach a diameter of 3 meters. When small fish enter this range, it is difficult for them to escape. The Japanese spider crab can live up to 100 years old, which can be regarded as the largest and longest-lived arthropod in the world. 192 1 year, people have captured the largest spider crab so far, with a weight of 4 1 pound and an amazing arm length of 19 feet.

The giant body of the spider crab is really scary. Every time it lays eggs, it will return to the beach. For self-protection, the spider crab may hurt tourists who come to play. However, spider crabs move slowly and are often hunted by fishermen.
