How does the green anole see?

The green anole (Anolis carolinensis) is a reptile in the order not recorded. Its eyes belong to the vision type Diurnal reptile tetrachromat: 4 cones incl. UV with oil droplets, fovea(s); turtles' red droplets extend red sensitivity.

Measured in this species: colour, foveas, night vision and motion (flicker fusion). Measured core: measured values on at least 3 of the 6 dials. Every value below carries its evidence level and sources; nothing is typed by hand.

The six dials

Evidence levels: how the tiers work. "Measured" means a value measured in this species; "Estimated" values come from a close relative or an eye-size formula.
