Your sister calls you crying because she just hit an animal with her car, and she thinks it was a ring-tailed lemur. You calm her down by saying that:
lemurs exist in the wild only in Madagascar, so she probably hit a raccoon

none of those monkeys have prehensile tails

in the superfamily Hominoidea
