Lobster claw

Lobster claw in reality.

The lobster with its claw probably cannot crush the bone in a human finger, but if it should grip a finger joint it can exert enough pressure to break the joint. When a lobster uses its claws, it pulsates between a grip and release action.The common crab on the other hand takes a grip and holds fast. It is therefore more unpleasant being pinched by a crab than a lobster.
    When a human pinches something between its thumb and finger, a lot of energi is used. Try yourself and you will notice that your fingers became tired quickly. A lobster or crab can pinch quite firmly without using a lot of energy because their muscles are constructed in another way.
