Nope, nobody who has handled the O' in the picture has been bitten. And Becki as you said they , if scared, they do open their mouth and act all mean and oooo so very vicious! But it is part of their "big" act! Wild Opossums when confronted will start with the "I am gonna bite the heck out of you pose" then go straight into the "oooo hey I think I am SOoooo very SICK"-so you dont want to eat me routine., this portion of the act they will froth at the mouth wobble back and forth hold their mouth all the way open, and even wobble enough to fall over, this act is so very convincing that it has convinced many of fellow humans that opossums are mainly sick diseased and rabid animals. A heck of an act . Unfortuntaly too good sometimes, the ironic thing is that Opossums are one of the very few animals that are NOT a rabies carrier!! (it is very very rare that any o' has rabies , a fact that is studied by the scientific people on how this is possible.)
The final act of this little series is the most common.. "PLAY OPOSSUM!" this is where the little guy or gal flops over and plays dead. *UGH*-*FLOP!* Opossums can play dead for up to 4 hours!!!!
Of course I have to say a disclaimer.. Any wild animals CAN and probably WILL bite you. And should never be approached. If sick or injured GET HELP just because they are not rabies CARRIERS doesnt mean one might not be sick or have a serious issue with it's health. This little opossum has been around people since it was very very young it doenst know to look or act mean!
