Unintentionally, tonight I found a crab while walking around monitoring the shrimp aquaculture area in the coastal area. The crab I found this time is the biggest I ever found in early 2018. It weighs almost 2 kg. Now I've tied up and I put in a small bucket.
Crabs are animals of ten-legged crustaceans. He is known to have a belly hidden beneath his chest. The body of the crab is protected by a very hard outer frame, made up of chitin, and armed with a pair of claws. Ketam is another name for crabs.
This animal is found in all the oceans of the world. Kind of crabs are varied, there are freshwater crabs, there are also ground crabs, especially in tropical regions. In addition to Crab, there are other types that are almost similar, called Rajungan. The crab is a crab that lives in the waters of the sea. He rarely goes to the beach.
In addition to the above two types, there is another name yuyu, namely crab inhabitants of freshwater (rivers and lakes), usually small body shape.
True crabs have five pairs of legs, the first pair of legs being modified into a pair of claws and not used for movement. In almost all types of crabs, the belly is folded under the cephalothorax. The crab mouth portion is covered by a flat maxilliped, and the front of the carapace does not form a long rostrum. Crab gills are formed from flat plates, similar to gill shrimp, but with different structures.
