Lobster Fact:
Lobsters usually move around and hunt for food at night. It was once thought that lobsters were scavengers, and ate primarily dead things. However, lobsters are really more opportunists, catching mainly fresh food which includes fish, crabs, clams, mussels, sea urchins. Lobsters are also cannibalistic and sometimes will eat other lobsters.
