Some cultures even considered the lobster an aphrodisiac, enhancing the power and charms of men, while for women it enhanced conception. We now know, that along with being a wonderful main course, the lobster is also a great critter for scientific studies. At each molt, the lobster's entire neuromusculatory system undergoes remodeling. Given that lobsters show few conventional signs of aging or of muscular disease, they are a very interesting animal for researchers who are trying to understand how neuronal synapses can bypass conventional aging that slows down neural transmissions.
Lobsters are also good models for studies on aggression.
These fights have extremely interesting consequences for the combatants. If a previously-fought lobster is then placed into another staged fight, its behavior is dependent upon its status from the previous fight. In other words, previous losers lose or refuse to fight with a new opponent. In the case where losers are pitted against other losers, no fights occur. Winners again win, unless they are pitted against another winner.
