Pipa crab is a famous specialty in Hainan, and its scientific name is "frog crab". Because of its peculiar appearance, fishermen in its producing area also call it "Qiong beast crab". Its logo is as follows: the head and breastplate are frog-shaped, like a lute, with strong and symmetrical pliers, four pairs of front legs, flat and shovel-shaped knuckles, and soft hair. The biggest difference from other crabs is to walk straight, not run sideways. Hainan's main producing area is in the harbor area of Lingshui New Village. The fishing season is around March every year. At this time, the pipa crab is big and delicious, especially boiled and steamed.
