Coconut Crab

Live crabs are often boiled. In 2005, Norwegian scientists concluded that lobsters cannot feel pain. However, later research suggests that crustaceans are indeed able to feel and remember pain.
Classification
The infraorder Brachyura contains 6,793 species in 93 families, as many as the remainder of the Decapoda. The evolution of crabs is characterised by an increasingly robust body, and a reduction in the abdomen. Although many other groups have undergone similar processes, carcinisation is most advanced in crabs. The telson is no longer functional in crabs, and the uropods are absent, having probably evolved into small devices for holding the reduced abdomen tight against the sternum.
