if you get the legs. Possibly really hurt one or 2 and have the other(s) decide to leave you alone. You would have to come at them absolutely crazy though, any hesitation and you don't win. Elephant would get you quickly I would think. 30x30 cage gets really small with one of those in with you. The chimps are too many and freakishly strong. However, if you could really hurt a couple of them right off the bat(pun intended) maybe they decide to leave you alone.
