SummaryThe deep-sea bioluminescent squid, Watasenia scintillans, has three visual pigments: The major one (A1 pigment) is based on retinal and has λmax = 484 nm, the second one (A2 pigment) is based on 3-dehydroretinal and has λmax = 500 nm, and the third one (A4 pigment) is based on 4-hydroxyretinal and has λmax = 470 nm. The distribution of these 3 visual pigments in the retina was studied by HPLC analysis of the retinals in retina slices obtained by microdissection. It was found that A1… Expand

Compensation for longitudinal chromatic aberration in the eye of the firefly squid, Watasenia scintillans
TLDR
It was found that the lens of W. scintillans is virtually free of LSA and uncorrected for LCA, and the eye does not suffer from LCA because of a banked retina, which is an excellent solution for the firefly squid. Expand
Physiological response of the eye to different colored light-emitting diodes in Japanese flying squid Todarodes pacificus
TLDR
The results suggest that the eyes of T. pacificus react in different ways to various LED light colors, where the first reaction to a lighting change is the pupillary response, and pigment migration occurs only if the illumination continues. Expand
An investigation of the phototransduction cascade and temporal characteristics of the retina of the cuttlefish, Sepia officinalis
Name: Lisa Nelson Title: An Investigation of the Phototransduction Cascade and Temporal Characteristics of the Retina of tlie Cuttlefish, Sepia Officina/is Cephalopods have extremely well developedExpand
The retinular responses of common squid Todarodes pacificus for energy efficient fishing lamp using LED
TLDR
From results, blue light may be regarded as an excellent luring source as the retina of squid is highly sensitive to it, but it cannot be determined as the most ideal LED color for the purpose of catching fish. Expand
Comparative visual ecology of cephalopods from different habitats
TLDR
A new protocol for photoreceptor microspectrophotometry (MSP) is introduced that overcomes the difficulty of bleaching the bistable visual pigment and that reveals eight coastal coleoid cephalopods to be monochromatic with λmax varying from 484 to 505 nm. Expand
Early evolution of multifocal optics for well-focused colour vision in vertebrates
TLDR
Jawless fishes (Agnatha; lampreys and hagfishes) most closely resemble the earliest stage in vertebrate evolution and lamprey-like animals already existed in the Lower Cambrian, suggesting that the last common ancestor of all vertebrate lineages possessed a complex colour vision system. Expand
Changes in cuttlefish retinal sensitivity during growth
TLDR
The cuttlefish retina was found to be 100 times more sensitive to flashes of blue light than yellow; however animals of 7 cm mantle length demonstrated an enhanced sensitivity to blue light, when compared to smaller or larger animals. Expand
Quantum mechanical/molecular mechanical structure, enantioselectivity, and spectroscopy of hydroxyretinals and insights into the evolution of color vision in small white butterflies.
TLDR
A(3)- and A(4)-retinals are theoretically incorporated into squid and bovine visual pigments by use of the hybrid quantum mechanics/molecular mechanics [SORCI+Q//B3LYP/6-31G(d):Amber96] method, and insights into structure, enantioselectivity, and spectroscopy are gathered and presented for the first time. Expand
Evolution of opsins and phototransduction
TLDR
This work discusses the evolution of the counterion, the reduction of agonist binding to the receptor, and the molecular properties that characterize rod opsins apart from cone opsins, and shows how the advances in molecular biology and biophysics have given insights into how evolution works at the molecular level. Expand
Photoreception in Ambulacraria: A comprehensive approach
TLDR
A mechanistic model for understanding simple photodetection is proposed based on the pluteus larva of the sea urchin, which has been chosen as a model for answering the questions of photoreceptor systems of the earliest primary larvae. Expand

Adaptation of a deep-sea cephalopod to the photic environment. Evidence for three visual pigments
TLDR
The small area of the ventral retina containing two visual pigments is thought to have a high and broad spectral sensitivity, which is useful for distinguishing the bioluminescence of squids of the same species in their environmental downwelling light. Expand
4-Hydroxyretinal, a new visual pigment chromophore found in the bioluminescent squid, Watasenia scintillans.
TLDR
A new retinal derivative, 11-cis-4-hydroxyretinal, is identified as the chromophore of the third visual pigment of the squid. Expand
The Rhodopsin-Porphyropsin Visual System
The light-absorbing properties of visual pigments determine the sensitivity of the eye to various parts of the spectrum. An animal with a red-absorbing pigment is sensitive to red light. Conversely,Expand
Visual pigments in the individual rods of deep-sea fishes
TLDR
The visual pigments in the rods of 15 species of deep-sea fish were examined by microspectrophotometry and the λmax of these pigments suggest they give the fish maximum sensitivity to the ambient light in the deep, blue ocean waters where they live. Expand
Assessing the Fitness of Visual Pigments for their Photic Environments
In the dictionary sense a pigment is a substance that is coloured to the human eye. Colour is so striking a sensation that it was once thought to be an attribute of the “coloured” substance itself.Expand

Analysis of retinal and 3-dehydroretinal in the retina by high-pressure liquid chromatography.
TLDR
A sensitive analytical method was developed in order to study the rhodopsin-porphyropsin system in the eye and the results agreed with those obtained from the bleaching kinetics of visual pigment extracted with detergent. Expand
Amino acid sequence of the retinal binding site of squid visual pigment.
TLDR
In this experiment the retinylpeptides of eleven amino acid residues were isolated by monitoring the absorbance spectrum of the reduced retinal Schiff base without using radio-active [3H]retinal. Expand
[63] Measurement of the vitamin A cycle
TLDR
A number of colorimetric techniques for measurement of vitamin A are described, and in relation to the visual system the Carr–Price reaction is still one of the most useful in that it permits measurement of vitamins A1 and A2 simultaneously and is independent of the isomeric configuration and state of esterification.

Seasonal variation of the vitamin A2-based visual pigment in the retina of adult bullfrog,Rana catesbeiana
TLDR
Visual pigment composition was determined by HPLC analysis over a one-year period in the adult bullfrog (Rana catesbeiana) in Japan and in Japan, the vitamin A2-based pigment increased in November and reached a maximum of 32-36% between January and June. Expand
