Once they molt, they're called new-shell lobsters. Culls are lobsters that have lost one claw. Molting allows the lobster to grow new body parts, like legs or claws, that might have been lost. It takes several years for a lobster to regenerate a claw to full size, but eventually a whole new, correct-sized claw can be grown. Lobsters eat primarily fresh food, which includes some 100 different animals and plants.
Lobsters smell food or bait by using the four small antennae located on the front of it's head.
Tiny hairs on the legs are also used for finding food. One claw is sharp and pointed and is called the ripper claw because it is used to tear food apart. The other claw, which is rounder and rather larger, has a rounded crushing surface and is called, not surprisingly, the crusher claw. Both claws are very powerful, and it could hurt to be snapped by either one. That's why, when lobsters are caught, a special rubber band is placed around each claw.
