Morphology of the retina in deep‐water fish Nezumia sclerorhynchus (Valenciennes, 1838) (Gadiformes: Macrouridae)

The results of this study suggest that the retina of Nezumia sclerorhyncus exhibits high visual sensitivity and that vision is a sense that plays an important role in its behaviour.

Observations on the retina and ‘optical fold’ of a mesopelagic sabretooth fish, Evermanella balbo

The accessory retina of Evermanella balbo is significantly thinner, and less well-developed than the main retina, and is on this dorsal accessory retina that light traversing the ‘optical fold’ most likely falls, facilitating the detection of moving objects in the ventro-lateral field of view.

Ontogenic retinal changes in three ecologically distinct elopomorph fishes (Elopomorpha:Teleostei) correlate with light environment and behavior

A developmental paradigm in elopomorph fishes in which retinas are rod-dominated in larvae, but undergo periods of later cone genesis is demonstrated, suggesting some degree of developmental plasticity influenced by the light environment.

Straying from the flatfish retinal plan: Cone photoreceptor patterning in the common sole (Solea solea) and the Senegalese sole (Solea senegalensis)

A loss of cone mosaic patterning in species that are primarily nocturnal or dwell in low light environments as is the case for the common sole and the Senegalese sole is indicated.

The Cone Opsin Repertoire of Osteoglossomorph Fishes: Gene Loss in Mormyrid Electric Fish and a Long Wavelength-Sensitive Cone Opsin That Survived 3R

Phylogenetic analysis shows that the evolution of green-sensitive LWS opsins in these two teleost groups derives from a common ancestral L WS opsin that acquired green sensitivity.

The Mormyrid Optic Tectum Is a Topographic Interface for Active Electrolocation and Visual Sensing

The known neurosensory upstream circuitry was used to suggest a model of how a defined spot in the peripheral sensory world comes to be represented in a common associated neural locus both in the NL and the TeO, thereby providing the neural substrate for cross-modal object recognition.



Bipolar cells in the “grouped retina” of the elephantnose fish (Gnathonemus petersii)

Observations suggest that cone vision has a spatial acuity better than the “bundle grain”; in rod dominated vision the resolution matches that of the bundles; for this pathway, the hypothesis of the bundle as a functional unit is confirmed.

Retinal organisation in goldeye and mooneye (Teleostei: hiodontidae).

It is suggested that all non deep-sea fishes with bundled receptors have duplex retinas and the adaptive mechanisms for vision in turbid waters are based on different morphological means as illustrated by the comparison with Stizostedion.

The retinal tapetum is discussed in relation to those in other fishes, particularly those which also have receptor groups, and conclusions are drawn about their functional implications.

On the eye of the Goldeye Hiodon alosoides (Teleostei: Hiodontidae)

In the eye of the Goldeye the photoreceptors are arranged in bundles and the pigment epithelium contains a massive reflector or tapetum lucidum, suggested that the crystallites form a diffuse reflector backscattering light into the rods; and that the rodlets reflect light regularly from their surfaces into the Photoreceptor bundles.

Unique photoreceptor arrangements in a fish with polarized light discrimination

Optin expression studies indicated that all cones express middle‐to‐long wavelength opsins, with long and lateral cones possessing a different opsin from that in short and central cones, confirming the potential for color vision and suggesting that the unique cone topography in the northern anchovy retina may underlie a visual system with segregated color and polarization detection channels.

Duplex Retina in the Mesopelagic Deep‐Sea Teleost Lestidiops affinis (Ege, 1930)

Structural comparisons with certain other deep-sea teleosts suggest the likely presence of a retinal tapetum in L. affinis, i.e. each single cone or rod bundle is situated in a reflecting pit formed by the RPE, with a discrete reflector apposed to the tip of each cone outer segment.

Grouped, stacked rods and tapeta lucida in the retina of Japanese anchovy Engraulis japonicus

The retina of the Japanese anchovy is thought to be highly sensitive and well adapted to a dim light environment and has a retinal tapetum lucidum composed of guanine and hypoxanthine.

Fine structure of the retinal epithelium and retinal tapetum lucidum of the goldeye Hiodon alosoides

The fine structure of the retinal epithelium of the goldeye has been investigated with electron microscopy in both the light- and dark-adapted condition and Circadian changes are noted in the morphology of the myeloid bodies and mitochondria and in the location of the epithelial cell nucleus.
