I've heard that an hungry octopus when lacking food can eat its own arm or two . Is that true? I know that when they lose an arm a new one grows back, so how long does it take to grow back to full size? if it goes back to full size that is.
Eating oneself (in octopus speak) is called autophagy; it is, as far as i can ascertain, not uncommon practice in stressed animals.

IMHO your assessment is excellent. The only point with which I disagree is your inference that all coping mechanisms are counterproductive. Stress (apart from that which is life-threatening) inspires coping. Rather than self-destruction, it is self-preservation. JMO.. a.f.TaningiaDanae said:I am neither a psychologist nor a marine biologist..I think stressors which do not allow an individual organism to lash out at the actual source, may turn the aggression inward to self-destructive behavior, which in turn releases endorphins that enable the organism to "cope" -- albeit in a very counterproductive way -- with the situation.
