WORLD'S BIGGEST CRABS

THE BIGGEST CRAB IN THE WORLD IS....
Crabs come in all different shapes and sizes, but the crab animal that is the biggest crab, is the Japanese Spider Crab. The Japanese spider crab has the greatest leg span of any arthropod, reaching 3.8 metres (12 ft) from claw to claw. The body may grow to a size of 40 cm or 16 in (carapace width) and the whole crab can weigh up to 19 kilograms (42 lb).
The males have the longer chelipeds; Females have much shorter chelipeds, which are shorter than the following pair of legs. Apart from its outstanding size, the Japanese spider crab differs from other crabs in a number of ways. The first pleopods of males are unusually twisted, and its larvae appear primitive. The crab is orange, with white spots along the legs. It is reported to have a gentle disposition, despite its ferocious appearance.
IS IT DANGEROUS?
The crab was known to the Japanese for the serious injuries it can cause with its strong claws.
DO PEOPLE EAT THEM?
The Japanese spider crab is "occasionally collected for food," and even considered a delicacy in many parts of Japan and other areas in the region. A total of 24.7 tonnes (54,000 lb) were collected in 1976, but only 3.2 tonnes (7,100 lb) in 1985. The fishery is centred around Suruga Bay and they are caught using small trawling nets.
The population has decreased in number, forcing fishermen into exploring deeper waters to catch them. Harvesting of the crab is forbidden during the spring, when crabs move to shallower water to reproduce. Populations of this species of crab have diminished over recent years and there are many efforts to protect them.
