How does the spotted cleaner shrimp see?
The spotted cleaner shrimp (Periclimenes yucatanicus) is a crustacean in the order Decapoda. Its eyes belong to the vision type Crustacean (mantis shrimp, crab).
Measured in this species: sharpness. 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, but one of them sees ultraviolet.
- Its sharpest vision resolves 0.1 cycles per degree: the finest stripe pattern it can tell apart from grey.
- It stops seeing flicker at 44 Hz, against 60 Hz for people in this dataset, so fast motion looks choppier to it.[6][7]
- 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: 390 nm (UVS), 496 nm (MWS (green)), 555 nm (LWS (long)) receptor set of nearest measured relative Palaemon vulgaris (same family Palaemonidae) | Estimated | [1] |
| Ultraviolet yes: at least one receptor peaks in the ultraviolet | Estimated | ||
| Sharpness | Acuity 0.1 cycles per degree median of 1 compilation rows (method priority rule) | Measured | [2] |
| Angle between facets 1.6° median of 1 relatives in class Malacostraca: Phronima sedentaria | Group default | [3] | |
| Eye type compound eye | |||
| Field of view | No value in the catalogue. | ||
| Sharp zones (foveas) | No value in the catalogue. | ||
| Night vision | Activity pattern nocturnal group default: mode of tier-A values in vision type V27 within phylum Arthropoda (1 species: Ligia exotica) | Group default | [4] |
| Rods vs cones no rods (invertebrate photoreceptors) | Group default | [4] | |
| Motion (flicker fusion) | Flicker fusion frequency 44 Hz median of 2 relatives in family Palaemonidae: Ancylomenes pedersoni, Urocaridella antonbruunii | Estimated | [5] |
