Social Structure
The Barrier Reef Anemonefish live together in a social structure within a single anemone. A dominant female is the largest member of the group, and her mate, the dominant male, the second largest. There are also up to four lower-ranking males. There is little aggression from the large female toward the males, but fierce in-fighting between the males maintains the pecking order. The lowest ranking male may be driven out and forced to seek a place in a group within another anemone host or die. If the female dies, the dominant male assumes her position within the hierarchy and over the course of a few days changes sex. In the wild they may live 6–10 years, but captive species have survived for 18 years.

Famous quotes containing the words social and/or structure:
“It’s frightening how easy it is to commit murder in America. Just a drink too much. I can see myself doing it. In England, one feels all the social restraints holding one back. But here, anything can happen.”
—W.H. (Wystan Hugh)
“Agnosticism is a perfectly respectable and tenable philosophical position; it is not dogmatic and makes no pronouncements about the ultimate truths of the universe. It remains open to evidence and persuasion; lacking faith, it nevertheless does not deride faith. Atheism, on the other hand, is as unyielding and dogmatic about religious belief as true believers are about heathens. It tries to use reason to demolish a structure that is not built upon reason.”
—Sydney J. Harris (1917–1986)
