In summer, I like to support my body with my feet in the high tide zone, and when it is cold, I lurk in the sand, only showing my eyes. As a kind of euryhaline, the blue crab can grow normally at a salinity of 5-33‰, and the suitable salinity is 14-27‰. Studies have shown that the adaptability of blue crabs to salinity varies with the salinity environment in the waters where their parents live.
