Lobster Fact:
All Lobsters living together, whether in tanks or in territories on the ocean bottom, soon establish a hierarchy of dominance. They usually fight once, sometimes with great ferocity, to determine who will become the boss. The winner, not surprisingly, is usually the larger and more aggressive one, but occasionally a smaller but tougher opponent wins. After that, whenever the two lobsters meet, the winner whips his antennae across the other lobster’s claws. The loser grovels in the sand until the dominant one passes by. In captivity, subordinate lobsters often suffer slower growth and less frequent molting. It could be the result of stress or less food. The dominant lobster gets first choice of shelter, food, and mates. In captivity, the female lobsters actually stagger their molts in order to wait their turn to mate with the dominant male!
