Description:
Scylla serrata, known as the swimming crab, is characterized by its oval-shaped carapace. This carapace features four distinct triangular frontal teeth located between the crab’s eyes, and on each side, it bears a total of nine anterolateral teeth. The chelipeds, which are the claw-like legs, are particularly massive and smooth, and they are noticeably longer than the other legs. The palm of the chela, or claw, is equipped with two spines on its dorsal margin and two more spines where the movable finger, called the dactyl, connects.Further down the claw, at the carpus (wrist), there are two prominent spines on the outer margin. Moving to the merus, which is the forearm, there are three large spines along the anterior border and two smaller spines on the posterior border. The legs of Scylla serrata are stout and moderately compressed, with the fourth pair being specially adapted for swimming. In terms of sexual dimorphism, the male crab’s abdomen is narrow, with segments 3 to 5 fused together. In contrast, the female crab exhibits a broadly oval-shaped abdomen.The coloration of S. serrata varies, ranging from shades of purple to green and brownish or black.
