Crawfish do not ever come out of their shell. The shell is a type of exoskeleton.
All animals walk around naked except us. Humans are the only animal that wears clothes. If you are asking whether a turtle can come out of the shell, then the answer is no. The shell is part of the turtle, and if the shell is peeled off, part of the turtle is ripped off and the animal will die. It would be like pulling off your ribcage.
