Also, that "male Lobster" example you gave Alex is bulls**t
Infact, here's something I read about male lobsters lol
As for male lobsters being so helpful to one another, one of the reasons their claws are rubber-banded is because they can be fairly cannibalistic - given a chance they'll eat each other. A study of the stomach contents of lobsters determined that a good portion of a lobster's diet is other lobsters.
