Opossums, a Fox, and a Coyote?

I went down a small rabbit hole (opossum hole?) while writing this post trying to figure out whether I should use "possum" or "opossum" and whether to use "a" or "an" in front of "opossum". I read articles from mentalfloss, grammarly, and english.stackexchange.com before deciding on "an opossum".

Fortunately, a fox has no such confusion. It's the next animal on this brief tour:

And finally, a coyote... I think?

That's the end of the tour. No skunks or raccoons yet, but I'm sure they're out there.
