Scylla serrata (often called mud crab or mangrove crab, although both terms are highly ambiguous and black crab) is an ecologically important species of crab found in the estuaries and mangroves of Africa, Australia and Asia. In their most common forms, their shell colours vary from a deep, mottled green to very dark brown. Scylla serrata is a swimming crab with an oval carapace. The carapace bears four triangular frontal teeth between the eyes and nine anterolateral teeth on each side. The chelipeds (claw-legs) are massive and smooth, and longer than the other legs. Mud crabs are prized by recreational fishers for their impressive size and delicious taste. MOQ 1 MT Supplied from Sri Lanka, Indonesia and Vietnam.
