She posted pictures of the bite marks that look pretty horrific. I assume she signed a release, but, here in the US the spa might still be liable due to ignoring the monkey's predilection to bite. "Every dog gets one bite" would probably apply to "pet" monkeys. Nevertheless, you are assuming a certain amount of risk when you go into the jungle in another country. Interesting in terms of the legal issues but a really awful thing to have happened on vacation.
