Humans cannot see ultraviolet light, but many arthropods and vertebrates can because they have a single photo-receptor with a peak sensitivity to light at wavelengths of around 350 nanometres (ref. 1). Here we use electrophysiological methods to investigate the vision of the mantis shrimp, Neogonodactylus oerstedii. We find that this marine crustacean has at least four types of photoreceptor for ultraviolet light that are located in cells of the eye known as R8 cells. These photoreceptors are… 

A Different Form of Color Vision in Mantis Shrimp

TLDR
Stomatopods appear to use a color identification approach that results from a temporal scan of an object across the 12 photoreceptor sensitivities, allowing for extremely rapid color recognition without the need to discriminate between wavelengths within a spectrum.

Filtering and polychromatic vision in mantis shrimps: themes in visible and ultraviolet vision

TLDR
Stomatopod crustaceans have reached an evolutionary extreme in their use of filter mechanisms to tune photoreception to habitat and behaviour, allowing them to extend the spectral range of their vision both deeper into the ultraviolet and further into the red.

Sensory adaptation: Tunable colour vision in a mantis shrimp

TLDR
In the mantis shrimp Haptosquilla trispinosa, which occupies a range of depths in the ocean, long-wavelength colour receptors are individually tuned to the local light environment.

Cerebral photoreception in mantis shrimp

TLDR
It is shown that the mantis shrimp Neogonodactylus oerstedii has functional cerebral photoreceptors, which expands the suite of mechanisms by which mantisrimp sense light and may contribute to shelter-seeking behaviors and other functions.

Behavioural evidence for polychromatic ultraviolet sensitivity in mantis shrimp

TLDR
It is found that H. trispinosa can discriminate stimuli peaking near 379 nm versus 351 nm in wavelength, suggesting that their wavelength discrimination in the UV is comparable to their performance in the human-visible range.

The Ecology of Teleost Fish Visual Pigments: a Good Example of Sensory Adaptation to the Environment?

TLDR
The aquatic environment offers a natural laboratory for the study of visual ecology, as many fish probably modify their visual pigment complement, either during development or seasonally, as they change factors such as their feeding habits, geographical location, depth of habitat and photic environment.

Photoreception and vision in the ultraviolet

ABSTRACT Ultraviolet (UV) light occupies the spectral range of wavelengths slightly shorter than those visible to humans. Because of its shorter wavelength, it is more energetic (and potentially more

Vision in the ultraviolet

TLDR
Amino acid sequence analysis of vertebrate VS/UVS pigments indicates that the ancestral pigment was UVS, with loss of UV sensitivity occurring separately in mammals, amphibia and birds, and subsequently regained by a single amino acid substitution in certain bird species.

Spectral tuning and the visual ecology of mantis shrimps.

TLDR
Results show that receptors of the peripheral photoreceptors, those outside the midband which are responsible for standard visual tasks such as spatial vision and motion detection, reveal the well-known pattern of decreasing lambdamax with increasing depth.

A unique colour and polarization vision system in mantis shrimps

TLDR
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.

A retina with at least ten spectral types of photoreceptors in a mantis shrimp

TLDR
The absorption spectra of the coloured filters and the visual pigments in frozen sections of retinae of a typical species, Pseudosquilla ciliata, of stomatopod crustaceans are measured using end-on microspectrophotometry.

The Compound Eyes of Mantis Shrimps (Crustacea, Hoplocarida, Stomatopoda). I. Compound Eye Structure: The Detection of Polarized Light

TLDR
Structural evidence is presented that stomatopod crustaceans have the receptors necessary for colour and polarization vision, and that all retinular cells in rows one to four of the mid-band, and the distal most retInular cells over most of the retina, are not sensitive to polarized light.

Tetrachromacy, oil droplets and bird plumage colours

TLDR
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.

Visual pigments, oil droplets and cone photoreceptor distribution in the european starling (Sturnus vulgaris)

TLDR
Microspectrophotometric measurements of retinal photoreceptors from the European starling revealed four classes of single cone, containing visual pigments with wavelengths of maximum absorbance, and a new polynomial for fitting visual pigment templates to ultraviolet-sensitive visual pigment data is given.

Optical properties of the clearest natural waters (200-800 nm).

TLDR
A comparative analysis and new data allow a consistent and accurate set of optical properties for the clearest natural waters and for pure fresh water and saltwater to be estimated from 300 to 800 nm.
