I’ve always been fascinated by the fact that chimpanzees are much, much, much stronger than humans. You never get that sense from watching TV and movies — largely because most actor-chimps are still babies and because no one wanted to seen Bonzo snap Ronald Reagans thighbone like a twig and then use it to fish for termites.

The attack that was in all the papers was truly horrifying and it was a useful reminder that chimps aren’t as cuddly as we often think. Apparently to chimps got out of their cages and were furious that an older couple was bringing a birthday cake for another chimp (though investigators are still a bit baffled by the whole incident). Here’s what the two chimps did to the husband — who protected his wife from the worst of the attack:

St. James Davis lost all the fingers from both hands, an eye, part of his nose, cheek, lips, and part of his buttocks in the ferocious attack, his wife, LaDonna Davis, told NBC’s “Today Show” Saturday. His foot was mutilated and his heel bone cracked.
