I did list them as holding American Martens.ZooAmerica's martens are American Martens, not Pine Martens. They are completely different species not just subspecies.
Kaleideum North in Winston-Salem NC and Animal Forest in Charleston SC also have otters.The Calvert Marine Museum in Maryland also has three North American River Otters
I'm not counting domestic species.Nobody has domestic ferret? Even as ambassador critters?
I think the river otter might be the most-kept wild mammal species in the USA.
Might well be, I'd imagine raccoon isn't too far behind.
Really? I can only think of a couple of places with them, probably no more than 10 AZA zoos at least. The otters have the crossover of being in zoos and aquariums, and it seems a lot of small museums that have just a few fish tanks also have otters to bring in visitors.
