How does the strawberry poison frog see?
The strawberry poison frog (Oophaga pumilio) is a amphibian in the order Anura. Its eyes belong to the vision type Amphibian motion detector.
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 three colour receptor classes, like most people.
- Its sharpest vision resolves 2.8 cycles per degree: the finest stripe pattern it can tell apart from grey.
- It stops seeing flicker at 16.9 Hz, against 60 Hz for people in this dataset, so fast motion looks choppier to it.[10][8]
- 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 3 receptor classes: 466 nm (SWS (blue)), 489 nm (MWS (green)), 561 nm (LWS (long)) species-v1.csv value measured in this species (not in tidy tables) | Measured (not re-verified) | [1] |
| Sharpness | Acuity 2.8 cycles per degree median of 1 relatives in order Anura: Lithobates pipiens | Group default | [2] |
| Field of view | No value in the catalogue. | ||
| Sharp zones (foveas) | No value in the catalogue. | ||
| Night vision | Activity pattern diurnal mode of 5 rows (of 5 rows): diurnal | Measured (not re-verified) | [3][4][5][6][7] |
| Rods vs cones cone-dominated nocturnal -> rod-dominated; crepuscular / cathemeral / mixed -> mixed; diurnal -> cone-dominated | Derived | [3][4][5][6][7] | |
| Motion (flicker fusion) | Flicker fusion frequency 16.9 Hz median of 2 relatives in order Anura: Rhinella marina, Lithobates clamitans | Group default | [8][9] |
