How Big is a Spider Crab?
WouterThe Japanese spider crab is the largest species of crustacean. It can be found in the Pacific ocean and can reach up to 12 feet in length. It is orange in color with white spots on its legs.
The Japanese spider crab is known to be gentle. These crabs can eat algae, plant material and mollusks. They are often seen crawling on the seabed. It has a carapace that is pear-shaped, with a sub-circular hole for the head. The body is also covered with spines, hairs and tubercles.
The body of a spider crab is usually matted with algae and sponges. They are scavengers, feeding on dead animals and plants. They do not make good hunters. Their legs are weak and can be easily ripped off by fishing nets.
Spider crabs live in sandy seabeds off the Honshu and Kyushu islands. Their shells are decorated with objects to help them camouflage. They also have long legs. They can dive up to 2,500 feet.
The legs of a Japanese spider crab can be up to twelve feet in length. This can increase as the crab grows. The crab can weigh up to forty pounds. The crab can live for up to 100 years. It is believed that the spider crab’s large size comes from its lanky legs.
The crabs molt each year to prepare for growth. Their new exo-skeleton hardens in two weeks. The moulting process leaves the crab vulnerable to predation.
