What water do crab live in?

Answer 1

They live in salt water, because they usually live in the ocean. I learned this in school.
I adopted a fiddler crab...TODAY! My teacher told me to buy salt water and they've been living in it for a long time.

Answer 2

depends on what kind of crab. if fiddler, red claw, or most small pet crabs, i believe brackish. if u mean hermit crab i dont think they need to live in water they just drink it hope this helps i had a red claw and it lived 3 months in brackish water wich i think is a normal lifespan 4 them.

find your answer in hear by reading and you also have more informtion:

Horseshoe crabs are arthropods which include the insects, Spiders, true crabs, and centipedes. Arthropods are divided into two major groups based on the first set of "postoral" (after the mouth) appendages: chelicerates and mandibulates. Mandibulate arthropods have "mandibles," in which the postoral appendages are jawlike (think of what an ant bites you with). Spiders, horseshoe crabs, and scorpions have chelicera (KELL-ISS-ERR-AH) which are feeding appendages which are jointed and sometimes possess a set of claws. The chelicera are used to push food into the mouth while mandibles are capable of cutting or grasping food.

Horseshoe crabs are jawless. The mouth is essentially a hole into the esophagus with muscles that open and close this opening. The mouth is located at the base of the legs which effectively surround it. The first segments of the legs are enlarged and covered with thick and hard bristles pointing inward toward the mouth. These bristles (gnathobases) act like a set of grinding tools as the animal is walking and they are used to "chew" food and direct it toward the mouth where the chelicera then finish the job of pushing the material into the mouth. From the mouth the food passes into the esophagus, a crop, a gizzard that grinds the food, the stomach, intestine and terminates in an anus located on the ventral side just in front of the telson.

• Horseshoe crabs are scavengers and feed on mollusks, worms and other benthic organisms. Because they grind food with their spiny leg segments they actually have to be walking to chew their food.
