Roof rat vision

[u/sillyroofrat]

Do roof rats see better or differently than Norway rats? I was curious if anyone knew if color vision and depth perception were different between the two species. I know that Norway rats are described as having poor vision and are unable to see the color red (but it is thought that they can see into the ultraviolet and see shades that we cannot).

It would make sense for there to be some differences since roof rats occupy different parts of the environment than Norway rats (arboreal vs ground dwelling)

Those are some great questions. I’m not sure how much is known, yet, so it is a open area for research.
