• note: cycles per degree is the number of cycles detectable per degree of visual angle
• shows UV light of various flowers (what bees can see...).

Note: Fish rods can retract if things are too bright.
Many fish have primarily rods for upper vision and cones for lower vision.

From: http://www.ratbehavior.org/RatVision.htm
Rats have just two types of cones (called "dichromatic" vision): a short "blue-UV" and the middle "green" cones (Szel 1992). The "green" cones' peak sensitivity is around 510 nm (Radlwimmer 1998), but the "blue" cones are shifted toward even shorter wavelengths than human blue cones, peaking at 359 nm. This means rats can see into the ultraviolet, they can see colors we can't see (Jacobs et al. 1991; 2001).

Rats don't have many cones, though -- 99% of the rat retina consists of rods, which sense only light and dark, and only 1% consists of cones (LaVail 1976), compared to a human's 5% and the dogs's 3% (Hecht 1987).
