The pike crab is known as "gazami crab" and commonly called "white crab" in some places. It is named because the cephalothoracic armor is in the shape of a pike. There are three protrusions in the center of the carapace, so it is also known as "pike crab with three warts". Male umbilicus pointed and smooth, chela grows, shell surface with green color; female umbilicus round with velvet, shell surface is ochre, or have spots. Pike crab meat is fat and tasty, has high nutritional value and economic value, and is suitable for seawater fattening temporarily. The cephalothorax is pike-shaped, almost twice as wide as long; the surface of the cephalothorax is covered with fine granules, with 2 granules transversely ronding and 3 warty protuberances; the frontal has 2 sharp teeth; the anterior lateral margin has 9 sharp teeth, and the final teeth are long and spiny, protruding outward. Chelicerae stout, length longer than width of cephalothorax; long segments prismatic, male long segments more slender, anterior margin with 4 sharp spines.
