Lobsters shed their shells, or molt. A female lobster can only mate just after she has molted. Lobsters can swim forward and backward. When they’re alarmed, they scoot away in reverse by rapidly curling and uncurling their tails. Because its nervous system is similar to that of grasshoppers and ants, lobsters are sometimes called “bugs.” When food is scarce, lobsters can turn cannibal and dine on smaller lobsters. Lobsters reproduce by laying lobster eggs. The eggs are carried by the female until they’re ready to hatch. Lobster eggs are called roe, just like fish eggs. Former President and First Lady George and Barbara Bush loved to eat lobster served up fresh at Mable’s restaurant in Kennebunkport, Maine. Slaves sometimes dined like kings, often eating lobster because it was plentiful and cheap. Maine lobsters are clawed lobsters, and have large, meaty claws. Spiny Caribbean lobsters have no claws and are sold mainly for their tails.
