How does the ornate dragon lizard see?
The ornate dragon lizard (Ctenophorus ornatus) is a reptile in the order not recorded. Its eyes belong to the vision type Diurnal reptile tetrachromat.
Measured in this species: colour and night vision. Measured colour or sharpness: a measured receptor set or acuity in this species; other dials come from relatives or group defaults. Every value below carries its evidence level and sources; nothing is typed by hand.

What stands out
- It has 4 colour receptor classes, including ultraviolet; people have 3.
- It stops seeing flicker at 34.6 Hz, against 60 Hz for people in this dataset, so fast motion looks choppier to it.[8][9]
- Activity pattern: diurnal.
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.
| Dial | Value | Evidence | Sources |
|---|---|---|---|
| Colour | Colour receptors 4 receptor classes: 375 nm (UVS), 440 nm (SWS (blue)), 493 nm (MWS (green)), 571 nm (LWS (long)) measured in this species | Measured | [1][2] |
| Ultraviolet yes: at least one receptor peaks in the ultraviolet | Measured | ||
| Sharpness | No value in the catalogue. | ||
| Field of view | No value in the catalogue. | ||
| Sharp zones (foveas) | Number of foveas 2 mode of species-v1 relatives in class Squamata: Anolis carolinensis, Furcifer pardalis | Group default | [3][4] |
| Fovea type central fovea, temporal | Group default | [3][4] | |
| Night vision | Activity pattern diurnal mode of 3 rows (of 3 rows): Diurnal; diurnal | Measured (not re-verified) | [1][5][6] |
| Rods vs cones cone-dominated nocturnal -> rod-dominated; crepuscular / cathemeral / mixed -> mixed; diurnal -> cone-dominated | Derived | [1][5][6] | |
| Motion (flicker fusion) | Flicker fusion frequency 34.6 Hz median of 15 relatives in class Squamata: Phrynosoma cornutum, Sphaerodactylus inaguae, Anolis cristatellus, Anolis gundlachi, Anolis pulchellus, Iguana iguana | Group default | [7][8][9][10] |
