...Ching-Wen Judy Wang; N. Justin Marshall ABSTRACT Stomatopods, commonly known as mantis shrimps, possess intricate colour vision with up to 12 photoreceptor classes arranged in four specialised ommatidia rows (rows 1–4 in the midband region of the eye) for colour perception. Whereas 2–4 spectral...

... that the response speed was similar between sexes and species and fused at around 100 Hz. Our results indicate that the three species have the ancestral insect retinal substrate for a trichromatic colour vision, based upon the UV, blue and green-sensitive photoreceptors, and lack any prominent adaptations related...

Visual performance is limited by thresholds, which are set by noise in photoreceptors and subsequent neural processing...

... Bird vision Colour vision Psychometric function Visual ecology For many animals, including primates, birds and insects, colour is an important cue to identify, recognise and evaluate objects, such as mates (e.g. birds: Hill, 1991 ; Hunt et al., 1999 ) or food (e.g. primates: Osorio...

..., but their colour vision capabilities remain unclear. Many studies have attempted to measure their spectral sensitivity and identify contributing retinular cells, but the existing evidence is inconclusive. We used electroretinogram (ERG) measurements and intracellular recordings from retinular cells to estimate...

Summary: Relative colour cues help chickens to recognize and discriminate colours when illumination colour is changed dramatically, thus improving their colour constancy performance. Colour vision...

After being trained for 2 days to take nectar at a yellow disc, an innately non-preferred colour, moths learned to select yellow over blue. The choice distribution between yellow and blue changed significantly from that of naive moths...
