How does the inagua least gecko see?
The inagua least gecko (Sphaerodactylus inaguae) is a reptile in the order not recorded. Its eyes belong to the vision type Colour or navigation at night.
Measured in this species: night vision and motion (flicker fusion). One measured dial: a value other than colour or sharpness is measured in this species; colour and sharpness are not measured here. Every value below carries its evidence level and sources; nothing is typed by hand.

What stands out
- It has three colour receptor classes, like most people, but one of them sees ultraviolet.
- It stops seeing flicker at 25.1 Hz, against 60 Hz for people in this dataset, so fast motion looks choppier to it.[8][9]
- Activity pattern: nocturnal.
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 3 receptor classes: 365 nm (UVS), 452 nm (SWS (blue)), 533 nm (MWS (green)) receptor set of nearest measured relative Teratoscincus scincus (same family Sphaerodactylidae) | Estimated | [1][2] |
| Ultraviolet yes: at least one receptor peaks in the ultraviolet | Estimated | ||
| 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 nocturnal mode of 2 rows (of 2 rows): Nocturnal; nocturnal | Measured (not re-verified) | [5][6] |
| Rods vs cones rod-dominated nocturnal -> rod-dominated; crepuscular / cathemeral / mixed -> mixed; diurnal -> cone-dominated | Derived | [5][6] | |
| Motion (flicker fusion) | Flicker fusion frequency 25.1 Hz median of 1 rows (no bright-light flag) (behavioural/whole-eye ERG rows; all rows: [25.1]) | Measured | [7] |
