Marsupials in the United States

I'm not aware of that but only because I was trying to find better picture to explain for the difference

Thank you for showing the comparison. You can use links in the future, though, if they aren't your photos. It seems to be a case much more like the owl monkeys than the coati, and they're likely being imported by the same people as the monkeys.

- Godwin's Gatorland had gray four-eyed opossum, which no long there anymore.

- Safari Tails, Science Alive, and Barn Hill Preserve had derby's woolly opossum.

Camal Safari is the only known place to hold bare-tailed woolly opossum in the US and never had Brown-eared woolly opossum (aka western woolly opossum).

- Plus not really error but there's another place named fragile planet wildlife park holding Derby's woolly opossum

Believe me, there are probably plenty of new information and errors in my list since my last update over a year ago.
If you really want to make your own list, then go ahead. I was considering updating this thread over the summer, but I’m just not sure I have the time to do so. If you really think you are up to the task, then go ahead.
I do want to warn you that there’s a reason so few members decide to do lists like these, as they can take months worth of research to complete. It’s especially hard for marsupials, as some species (especially Virgina Opossum) are almost impossible to keep track of and have very short lifespans, often popping up at small private locations rarely visited by members of this site.

I can see that

What's your basis for claiming these as Derby's, given none of these posts discuss differences?

To make things easier: Derby's (C. derbianus) and Brown-eared (C. lanatus) are easy to tell apart because the ears are consistently either unpigmented (in derbianus) or dark (in lanatus). Derby's is sometimes called the Pale-eared Woolly Opossum because of this. The two species cannot be reliably distinguished on colour of pelage because there is overlap in appearance. If source is known then there is just a relatively small area of overlap in distribution (only in the northwest of South America).

The Bare-tailed Woolly opossum (C. philander) can be very easily distinguished from the other two species, if the tail can be seen, by the caudal fur - in philander the tail is only furred at the base (hence the common name, because most of the tail is bare) whereas in the other two the fur extends down most of the upper surface of the tail.

The three species can be compared in this post: The Zoochat Photographic Guide to Monotremes and Marsupials
