The giant spider crab is the largest crustacean in the world, much like a giant poisonous spider. Because of translation errors, some people in China mistakenly call it "the giant killer crab". The width of an adult cancer can reach 30 cm. When it opens its sharp claws, it is more than 3 meters long and the largest can reach 4 meters.
The largest spider crab in the world is Ganzi, a cancer crab living in Japanese waters. They are also the largest living arthropods, and they are strange creatures living in the coastal waters of southeast Japan. China's "killer crab" refers to them. The largest crustacean known in the world lives at the bottom of the deep sea. Because there are no swimming limbs, air chambers and airbags, Ganzi, a crab, has no ability to swim or float at all, and can only crawl at an unpleasant speed on the seabed for food. So how does it "kill"?
In fact, "crab crab Ganzi Killing" originated from a translation error. Like many crabs, Ganzi, a crab with cancer, has the habit of scavenging, and often picks up the carrion of various animals at the bottom of the sea, so there is a common name "dead crab" in English. However, when "dead crab" was introduced into China, it was misinterpreted as "killer crab", which led to some untrue stories, leading to the saying that "killer crab kills people". In fact, Ganzi, a crab, can't kill people, but it is often caught by local fishermen in the Japanese waters where it is mainly distributed, and becomes human food or a "prisoner" in the aquarium.
