Starting on the Claws. Start with the legs and claws by gently pulling the lower part of each claw off. This often pulls all the inner claw meat with it, but it'll be attached to a hard, cartilaginous fin-shaped thing in the center.

The hemolymph cleans the internal parts when the crabs walk, and oxygen reaches them through the branchial chamber and the lungs. The heart pumps the hemolymph, which circulates within the body. When the heart eases up, the blood goes back to the core by pores called ostia. These pores replace the veins in the crab's body.
