Japanese Spider Crab

The Japanese spider crab, also known as the long-legged crab, is a delicacy. This arthropod has the gigantic legs seen on a creature of its kind. Two fossils of the same species found in Japan have been traced back to the Miocene era. 

The crustaceans can grow to about 12 feet stretching from limb to limb across their spindly legs. They are also masters of disguise and will often put other animals or sponges on their shells so that they can blend in with the seafloor as a defensive mechanism. Their reproduction is in spring, and the laws in Japan prohibit fishing for them during this period.
