This work examines the advantages of coloured oil droplets, UV vision and tetrachromacy for discriminating a diverse set of avian plumage spectra under natural illumination and finds that Discriminability is enhanced both by tetrACHromacy and coloured oil Droplets.
Monitoring coral bleaching using a colour reference card
A reference card that uses differences in coral colour was developed as an inexpensive, rapid and non-invasive method for the assessment of bleaching and offers the potential for rapid, wide-area assessment of changing coral condition.

Discovery of UV visual pigments with peak absorption at around 360 nm in teleost cone photoreceptors indicates that many teleost fishes may be adapted for vision in the UV range, and suggests that UV vision may well be co-opted through natural selection for other functions.

The spectra of colours in high spatial frequency patterns are often well designed to be very conspicuous to a colour vision system at close range but well camouflaged at a distance, and reef fishes use a combination of colour and behaviour to regulate their conspicuousness and crypsis.

Spectrophotometry of the lens, cornea, and humors for 195 species from 49 families found that the spectral composition of the light transmitted to the retina was most often limited by the lens (73% of species examined), and these species could possess true UV-color vision and hue discrimination.
A review of vertebrate and invertebrate ocular filters
The spectral information available to an animal’s visual system depends both on the wavelengths reaching its outer segments and the visual pigments contained within them. The former is governed not…
A unique colour and polarization vision system in mantis shrimps
- N. Marshall
- 9 June 1988
The arrangement of tiered microvilli in two other midband rows suggests that they provide a unique form of polarization vision, which may be adapted in a unique manner for colour and polarization vision.
