When it is cooked, all the pigments are masked except for astaxanthin, which is the background red pigment. There are also rare blue, red, white, and yellow-spotted Maine lobsters. All turn red when cooked. Lobsters increase in size about 20 per cent each time they molt. 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.
