Multiple spectral classes of photoreceptors in the retinas of gonodactyloid...
SummaryWe examined the compound eyes of 2 species of gonodactyloid stomatopods, Gonodactylus oerstedii and Pseudosquilla ciliata, using end-on microspectrophotometry of frozen sections of dark-adapted...
View ArticlePigments in Crustacean Compound Eyes
AbstractLike all photoreceptor organs, crustacean compound eyes produce pigments that interact with the light impinging upon them. Here, the term “pigment” refers to molecules that absorb light in the...

SummaryWe investigated optokinetic eye movements in 3 species of stomatopod crustaceans (Odontodactylus scyllarus, Pseudosquilla ciliata, and Gonodactylus oer stedii), all of which are members of the...
View ArticleCytoskeleton of retinular cells from the stomatopod, Gonodactylus oerstedii :...
AbstractRetinular cells of the compound eyes of stomatopods (mantis shrimps) contain screening pigment granules that migrate radially in response to light. To clarify the role of the cytoskeleton in...

Abstract. This study examines the diverse maximum wavelength absorption (λmax) found in crayfishes (Decapoda: Cambaridae and Parastacidae) and the associated genetic variation in their opsin locus. We...
View ArticleSpectral Sensitivity in Crustacean Eyes
AbstractEye designs and visual optics of crustacean eyes are the most diverse of all the major animal groups, as noted by Michael Land in his 1984 review. It is thus appropriate that their spectral...
View ArticleTuning of photoreceptor function in three mantis shrimp species that inhabit...
Abstract. Within single species of stomatopod crustaceans, visual pigment classes of homologous photoreceptors throughout the retina are identical in all individuals and do not vary with the spectral...
View ArticleTuning of photoreceptor function in three mantis shrimp species that inhabit...
Abstract. Visual pigments in many animal species, including stomatopod crustaceans, are adapted to the photic environments inhabited by that species. However, some species occupy a diversity of...
View ArticleSpectral sensitivity in a sponge larva
Abstract. Cilia at the posterior pole of demosponge larvae are known to cause directional swimming, sometimes in response to light gradients, but so far neither the spectral sensitivity of, nor the...

AbstractCrustaceans possess a huge variety of body plans and inhabit most regions of Earth, specializing in the aquatic realm. Their diversity of form and living space has resulted in equally diverse...
View ArticleVisual pigment absorbance and spectral sensitivity of the Mysis relicta...
AbstractVisual-pigment absorbance spectra and eye spectral sensitivities were examined in eight populations of opossum shrimp from different light environments. Four Finnish populations, two from the...
View ArticleEvolutionary variation in the expression of phenotypically plastic color...
AbstractMany animals have color vision systems that are well suited to their local environments. Changes in color vision can occur over long periods (evolutionary time), or over relatively short...

AbstractThe presence of a specialised dorsal rim area with an ability to detect the e-vector orientation of polarised light is shown for the first time in a nocturnal hymenopteran. The dorsal rim area...

AbstractHead-bobbing is a common and characteristic behavior of walking birds. While the activity could have a relatively minor biomechanical function, for balance and stabilization of gait,...
View ArticleExceptional Variation on a Common Theme: The Evolution of Crustacean Compound...
AbstractThe Crustacea contain an amazing, and often (to humans) bizarre, array of visual designs. This diversity includes many different examples of both simple and compound eyes, each with standard or...

AbstractAmong lampyrids, intraspecific sexual communication is facilitated by spectral correspondence between visual sensitivity and bioluminescence emission from the single lantern in the tail. Could...

AbstractBackgroundTools for high throughput sequencing and de novo assembly make the analysis of transcriptomes (i.e. the suite of genes expressed in a tissue) feasible for almost any organism. Yet a...
View ArticleSeeing double: visual physiology of double-retina eye ontogeny in stomatopod...
AbstractStomatopod eye development is unusual among crustaceans. Just prior to metamorphosis, an adult retina and associated neuro-processing structures emerge adjacent to the existing material in the...
View ArticleShort- and long-wavelength-sensitive opsins are involved in photoreception...
AbstractCrayfish have two classes of photoreceptors in the retinas of their reflecting superposition eyes. Long-wavelength-sensitive photoreceptors, comprised of microvilli from R1–7 cells, make up the...
View ArticleSpectral absorption of visual pigments in stomatopod larval photoreceptors
AbstractLarval stomatopod eyes appear to be much simpler versions of adult compound eyes, lacking most of the visual pigment diversity and photoreceptor specializations. Our understanding of the visual...
