Opossum Nipples

Anyone out there catch the crazy suggestion from Fringe the other night? Walter Bishop said an Opossum had 15 nipples. Could that be accurate?

I’m not much of an animal guy and if I was I doubt I’d know how many nipples an opossum had.

Does anyone know the truth?

Update (Seconds later after more google searching): GetRidOfThings seems to indicate they have opossums have 13 nipples.
