Offshore pike crab, blue crab.

and Chinese mitten crab (river crab, hairy crab, clear water crab) and so on.

A small group of crabs breed entirely in freshwater, and they mostly inhabit the rocks of mountain streams. There are also a few crabs, such as ground crabs, that can adapt to life on land, burrowing in damp mud holes, and migrating to the sea during the breeding season.

The vast majority of crabs are omnivorous. Some crabs are carnivorous, such as pike crabs, which can prey on fish, shrimp and molluscs.

Wait. A small number of crabs, such as the crab, scrape or filter feed on algae and organic debris.

The crabs are bought and put in the water.

After leaving the water, the crab will inhale a lot of air, the more air it inhales, the greater the area of contact between the gills and the air, and the water and air stored in the gills are spit out from both sides of the mouthparts and become foam, so as long as there is a little water, the crab can live for a long time.

There are many types of crabs, most of which live in water, so the crab you bought can also be preserved with water, but it should be noted that it should not be completely soaked in water, because although it can breathe with gills, the dissolved oxygen requirements of the water body are still relatively high, so the water level is best not to be submerged in its body.

Very few species such as drifting crabs and bow crabs can attach to wood or other floating objects living in the ocean, and many species live in symbiosis with other animals, such as cotton crabs and Guangong crabs, which often use the last two pairs of short steps to hold sponges, sea anemones, shells, etc. covered on the cephalothorax.

Xu Qingchan of the bean crab family often lives in the mantle cavity of mollusks or the ducts of polychaetes, while the Shanyin crab is completely contained in the gall sac of the stony coral, and the female crab is confined for life after mating, and the hatchling escapes through the unclosed orifice.

A small part of crabs grow and reproduce completely in fresh water, and most of them inhabit the rocks of mountain streams, such as brook crabs, Huaxi crabs, etc.
