The sand crabs are small sand crabs? Chinese sand crab

Chinese sand crab, nail width of about 4 centimeters, the body is thick and square, the back has white spots. The eyes are thick and short, without horns and teeth, the cephalothorax is square, and the back of the cephalothorax often has whitish markings, and the zoning is not obvious. Eyes stubby and short, without horny teeth. The chelicerae also lack a pronounced keel structure on the medial side of the metacarpal segment, hence the name. The footsteps are long and the two chelicerae are not symmetrical to each other. Although they move slowly, they will exert a faster-than-usual speed to hide back in the cave when their lives are in danger, and the slow langzhongs are quick to run for their lives when they are in danger.

The most special feature of the crab is the lack of a pronated ridge on the inner side of the cheliped's metacarpal segment, which is why some people refer to it as the flat-palmed sand crab, and this feature is the best way to distinguish it from other species of sand crabs. They are good at digging holes, the holes are mainly rounded, and there is often radial sediment sprayed out from the holes next to the holes. Because of his drought tolerance, he mostly burrows in drier mud flats above the high tide line, his habitat is drier than that of the scarab palm or horn-eyed sand crab, and he is active early in the morning or late in the evening, and sometimes at night.
