Robinson’s Mouse Opossum – biofluorescence

I’m a neophyte mammal-watcher- fairly experienced birder, so I’m not sure how unusual this note is.  In July 2024 I spent several days at a lodge on the Napo River in Ecuador. During a night walk we found what appears to be a Robinson’s Mouse Opossum, which is apparently not that unusual for the area.  We were all pretty surprised, though to see it flouresce in bright pink under a black light.  I’ve been reading that recently some mammals have been found to glow under UV, but I haven’t seen this species listed as one of those.

I’ve been actively interested in natural history for pretty much my whole life, with observations back to the late 1960s.  My primary interest has been birds, but that’s only because there are more of them and they’re easier to see and identify! But mammals, herps, insects are all on the radar for me.
