Intelligence paradox in octopus and squid



Most groups with high intelligence (humans and other apes, proboscids,
cetaceans, some birds such as parrots and crows) are relatively
long-lived. This makes sense, because a complex brain is a costly organ
to maintain and, having gone to the trouble of acquiring it, you would
presumably want a long time ahead of you to use it.

Octopus and squid also have large brains complex behaviour and in
laboratory tests show evidence of pretty high intelligence. Yet most
species live only one or two years. This seems rather wasteful.
