5. Opossum – The  opossum has a number of tricks up its defensive sleeve. It can play dead. It can foam at the mouth in an attempt to convince its predators that it is toxic. It can also emit a green anal fluid that smells nearly as bad as a skunk’s offensive spray. Opossums playing dead actually slip into a semi-comatose state, thus removing any excitement of the kill for a predator.
