Systems of colour vision are normally identical in all members of a species, but a single design may not be adequate for species living in a diverse range of light environments. Here we show that 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. The spectral sensitivity of specific classes of photoreceptor is adjusted by filters that vary between individuals. 

Tuning of photoreceptor function in three mantis shrimp species that inhabit a range of depths. I. Visual pigments

This work characterized the visual pigment complements of three species of stomatopod crustaceans, Haptosquilla trispinosa, Gonodactylellus affinis, and Gonodactsylopsis spongicola, which are unusual for this group in that each lives at depths from the subtidal to several tens of meters.

Tuning of photoreceptor function in three mantis shrimp species that inhabit a range of depths. II. Filter pigments

The changes in filter density and spectrum increased absolute sensitivity in retinas of animals living at greater depths, and tuned their long-wavelength photoreceptors for improved function in the bluer light available in deep water.

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

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.

Visual Adaptations in Crustaceans: Chromatic, Developmental, and Temporal Aspects

This chapter reviews the latest state of knowledge in crustacean vision concentrating on three areas: spectral sensitivities, ontogenetic development of spectral sensitivity, and the temporal properties of photoreceptors from different environments.

Evolutionary variation in the expression of phenotypically plastic color vision in Caribbean mantis shrimps, genus Neogonodactylus

The results indicate that adult stomatopods have evolved the ability to undergo habitat-specific spectral tuning, allowing rapid facultative physiological modification to suit ecological constraints.

Adaptive plasticity during the development of colour vision

Adaptive color vision in Pullosquilla litoralis (Stomatopoda, Lysiosquilloidea) associated with spectral and intensity changes in light environment

Pullosquilla litoralis is utilized, a member of the superfamily Lysiosquilloidea that has a wide depth range and major controlling element of the plasticity in lysiosquilloid stomatopod color vision appears to be light intensity rather than spectral distribution.

Visual system diversity in coral reef fishes.




Ultraviolet vision: The colourful world of the mantis shrimp

It is found that the mantis shrimp, Neogonodactylus oerstedii, has at least four types of photoreceptor for ultraviolet light that are located in cells of the eye known as R8 cells, indicating that the remarkable colour-vision system in these stomatopod crustaceans may be unique, as befits their habitat of kaleidoscopically colourful tropical coral reefs.

A unique colour and polarization vision system in mantis shrimps

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.

Spectral tuning and the visual ecology of mantis shrimps.

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

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.

Visual pigment changes in rainbow trout in response to temperature

Lower water temperature favors a higher proportion of porphyropsin in the retina of rainbow trout (Salmo gairdneri), regardless of the light conditions.

The ontogeny of ultraviolet photosensitivity in rainbow trout (Salmo gairdneri)

A comparison of the ocular media transmission of small and large trout eyes did not reveal large changes in the transmission of UV radiation through the eye, and spectral sensitivity in immobilized trout appeared to conform to the known blue-sensitive cone mechanism.
