|They are large Crustaceans and sojourned to a life inside shells. They live the early parts of their life in the ocean and when they reach adulthood they will leave the ocean to migrate to a distant land. From time to time they return to the sea to choose more suitable shell for themselves. The Chela Crab stores a certain amount of water within their body and when they attack their prey, they use it to spray jets of water to knockdown. An experienced hunter will usually avoid its heavy carapace attack its relatively fragile legs.
