What are the common crab species found in the sea?
Crabs are a seafood that many people enjoy eating. Crabs can be divided into three types: river crabs, lake crabs, and sea crabs, and under these three categories there are many species of crabs. So do you know what sea crab species there are? Below, let's get to know the crab species in the sea.
1. Swimming crab
In some places, the swimming crab is called "white crab" or "three-spot swimming crab". It is mainly distributed in Japan, Korea, the Malay Archipelago, the Red Sea, and most coastal areas of mainland China. The male swimming crab has a smooth, pointed abdomen and a bluish-green shell. The female has a rounded, fuzzy abdomen and an ochre-colored shell, sometimes with spots.
2. Mud crab
The mud crab is a crab that lives along the coasts of warm sea areas, widely distributed in the Indo-West Pacific region, including Japan, the Ryukyu Islands, mainland China, Taiwan, China, Southeast Asia, India, East Africa, South Africa, Australia, and other places.
3. Frog crab
In China, the frog crab is mainly distributed in the East China Sea and South China Sea areas. The frog crab's carapace is frog-shaped, longer than it is wide, with a very convex back densely covered with scale-like spines. The forehead is divided into 3 teeth; the middle tooth is large and triangular, while the side teeth are small.
4. Brown crab
The brown crab mainly lives on sandy or sandy-mud seabeds at depths of 30-100 m, and is mainly distributed in the Pacific Ocean and the waters of Hong Kong, China. The brown crab's carapace is light brown, with a semicircular reddish-brown pattern in the eye region, a reddish-brown spot on the outer side of the wrist and merus segments of the claws, and brown tips on the walking legs.
5. King crab
The king crab is also called the stone crab or rock crab. It is a crab that lives in cold sea areas. Because the king crab is huge in size, it has the reputation of "king of crabs". As a deep-sea crab, the king crab can live at depths of up to 850 m, and its survival water temperature is between 2-5°C.
6. Flower crab
The flower crab is named for the patterns on its shell. Flower crab sometimes specifically refers to the orchid crab (the male individual of the distant-sea swimming crab), but due to regional differences, the red flower crab (Charybdis feriata) is also called flower crab. Flower crab contains a large amount of nutrients essential to the human body, such as protein, fat, phospholipids, and vitamins, and is rich in nutrition.
Sea crabs are scavengers. When eating them, you first need to do a good job of removing cold and sterilizing the sea crab. Dead crabs and raw crabs should be avoided, and special groups such as those with colds, gallstones, and pregnant women should also not eat crabs.
