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.

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.

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.

Evolution of anatomical and physiological specialization in the compound eyes of stomatopod crustaceans

Maximum likelihood ancestral state reconstructions indicate that ancestral stomatopod eyes contained six midband rows and four intrarhabdomal filters, illustrating that the visual physiological complexity originated early in stom atopod evolutionary history.

Visual pigment diversity in two genera of mantis shrimps implies rapid evolution (Crustacea; Stomatopoda)

The variation within closely related species of the same genus implies that visual pigments can evolve rapidly in stomatopod crustaceans, andVisual pigments of the tiered rows of the midband span a larger spectral range in shallow-water than deepwater species.

Vision in two sympatric species of pullosquilla (stomatopoda, lysiosquilloidea) living in different depth ranges

The visual systems of two species of the lysiosquilloid stomatopod crustacean genus Pullosquilla living sympatrically in waters around the island of Moorea, French Polynesia were examined, with results indicating that the visual pigment in the main retina of P. thomassini had λmax at 467 nm, compared to 509 nm in the corresponding retinal region ofP.

Ultraviolet filters in stomatopod crustaceans: diversity, ecology and evolution

A broad survey of mantis shrimp reveals variability in ocular UV-filters, suggesting a complex evolutionary history for these pigments, and even greater visual complexity than previously appreciated in this group.

Intracellular Recordings of Spectral Sensitivities in Stomatopods: a Comparison across Species.

The spectral sensitivities across five species of stomatopods within the superfamily Gonodactyloidea are compared using intracellular electrophysiological recordings to show the similarities and the variations in the spectral sensitivity estimates previously obtained using microspectrophotometry.

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.

Eye Design and Color Signaling in a Stomatopod Crustacean Gonodactylus smithii

Color vision in G. smithii is therefore not exclusively adapted to detect its own color signals, but the spectral tuning of some photoreceptors enhances the contrast of certain color signals to a large enough degree to make co-evolution between color vision and these rather specific color signals likely.



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.

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

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.

Photosensitive and photostable pigments in the retinae of Old World monkeys.

Microspectrophotometric measurements of retinal receptors are reported for eight species of Old World monkey, finding that the trichromacy of frugivorous catarrhine monkeys may have co-evolved with a particular class of coloured fruit.

The Compound Eyes of Mantis Shrimps (Crustacea, Hoplocarida, Stomatopoda). II. Colour Pigments in the Eyes of Stomatopod Crustaceans: Polychromatic Vision by Serial and Lateral Filtering

These adaptations include brightly coloured intrarhabdomal filters, apparent lateral filters and a photoreceptor tiering system unique to the crustacea which allow the spectrum of light available to stomatopods to be sampled over a broad spectral range by receptors with narrowly tuned sensitivities.

Color vision in Lycaena butterflies: spectral tuning of receptor arrays in relation to behavioral ecology.

Males of two closely related, co-occurring species of Lycaena butterflies have dorsally blue or red-orange plus ultraviolet wings andVirgin females accept only conspecific males, probably chosen by wing color.

Visual pigments and the acquisition of visual information.

Significant differences between the cone sets of animals living within the same environment and colour vision polymorphism within a species suggest that visual tasks critical to survival or breeding success require particular visual pigment sets.

Visual Rhythms in Stomatopod Crustaceans Observed in the Pseudopupil.

The differences between these species, together with the results of other comparative research on visual rhythms in arthropods, suggest that circadian, rhythmic processes are involved in optimizing nocturnal eyes for maximum sensitivity and dynamic range.
