Sea snakes have evolved numerous anatomical, physiological, and behavioral adaptations to suit their wholly aquatic lifestyle. However, although sea snakes use vision for foraging and mate selection, little is known about their visual abilities. We used microspectrophotometry, light microscopy, and scanning electron microscopy to characterize the retinal photoreceptors of spine‐bellied (Lapemis curtus) and horned (Acalyptophis peronii) sea snakes. Both species have three types of visual pigment… 

Evolutionary transformation of rod photoreceptors in the all-cone retina of a diurnal garter snake

TLDR
It is proposed that these cone-like rods may have evolved to regain spectral sensitivity and chromatic discrimination as a result of ancestral losses of middle-wavelength cone opsins in early snake evolution, illustrating how sensory evolution can be shaped not only by environmental constraints but also by historical contingency in forming new cell types with convergent functionality.

Visual Pigments, Ocular Filters and the Evolution of Snake Vision.

TLDR
Positive selection was inferred at multiple sites in all three opsins, these being concentrated in transmembrane domains and thus likely to have a substantial effect on spectral tuning and other aspects of opsin function.

Multiple rod–cone and cone–rod photoreceptor transmutations in snakes: evidence from visual opsin gene expression

TLDR
It is concluded that photoreceptors with superficially rod- or cone-like morphology are not limited to containing scotopic or photopic opsins, respectively and future research will help to clarify the fundamental properties and physiology of photoreceptor adapted to function in different light levels.

Spectral Tuning in the Eyes of Deep-Sea Lanternfishes (Myctophidae): A Novel Sexually Dimorphic Intra-Ocular Filter

TLDR
It is suggested that this unique specialisation of yellow pigmentation in Lanternfishes acts as a filter to enhance contrast, thereby improving the detection of bioluminescent emissions and possibly fluorescence in the extreme environment of the deep sea.

Spectral sensitivity of cone photoreceptors and opsin expression in two colour-divergent lineages of the lizard Ctenophorus decresii

TLDR
Microspectrophotometry and opsin expression reveals four single cone classes without intraspecific differentiation in C. decresii, suggesting tetrachromacy in the species, and provides the first evidence of UV sensitivity in agamid lizards.

Comparative Study of Photoreceptor and Retinal Ganglion Cell Topography and Spatial Resolving Power in Dipsadidae Snakes

TLDR
The goal of the present study was to compare the density and topography of neurons, photoreceptors, and cells in the ganglion cell layer in the retinas of these two species using immunohistochemistry and Nissl staining procedures and estimate the spatial resolving power of their eyes based on the gangLion cell peak density.

The Evolution of Photoreceptors and Visual Photopigments in Vertebrates

TLDR
All classical vertebrate retinal photoreceptors have an evolutionary origin from ciliary cells and retain a modified cilium that links the inner and outer segments, with certain classes of cone opsins absent in certain lineages.

Multiple cone visual pigments and the potential for trichromatic colour vision in two species of elasmobranch

TLDR
The finding raises the possibility that some species are able to discriminate colour – a visual ability traditionally thought to be lacking in this vertebrate class – and it is evident that the visual ecology of elasmobranchs is far more complex than once thought.

Shedding Light on Serpent Sight: The Visual Pigments of Henophidian Snakes

TLDR
The presence of a duplex retina and the characterization of LWS, SWS1, and Rh1 visual pigments in henophidian snakes implies that “lower” snakes do not provide support for Walls' transmutation theory, unlike some “higher” (caenophidian) snakes and other reptiles, such as geckos.

The photoreceptors and visual pigments of the garter snake (Thamnophis sirtalis): a microspectrophotometric, scanning electron microscopic and immunocytochemical study

TLDR
The small single cones with the 360-nm pigment provide the garter snake with selective sensitivity to light in the near ultraviolet region of the spectrum, which might be important in localization of pheromone trails.

The photoreceptors and visual pigments in the retina of a boid snake, the ball python (Python regius)

TLDR
The photoreceptors and visual pigments of Python regius were studied using microspectrophotometry and scanning electron microscopy and the results are discussed in relation to the behavior of P. regius.

Rod-like Properties of Small Single Cones: Transmutated Photoreceptors of Garter Snakes (Thamnophis proximus)

TLDR
Current results suggest that small single cones of T. proximus may have evolved from ancestral rods, and secondarily acquired a cone-like morphology as adaptation to diurnality.

Colour vision and visual ecology of the blue-spotted maskray, Dasyatis kuhlii Müller & Henle, 1814

TLDR
Measurement of the spectral absorption of the rod and cone visual pigments of the blue-spotted maskray, Dasyatis kuhlii, using microspectrophotometry reveals that wavelengths below 380 nm do not reach the retina, indicating that D. kuhLii is relatively insensitive to ultraviolet radiation.

Retinal photoreceptors and visual pigments in Boa constrictor imperator.

TLDR
The photoreceptors of Boa constrictor, a boid snake of the subfamily Boinae, were examined with scanning electron microscopy and microspectrophotometry and the data indicate that wavelength discrimination above 430 nm would not be possible without some input from the rods.

Microspectrophotometric evidence for cone monochromacy in sharks

TLDR
It is shown that, while the spectral tuning of the rod and cone pigments of sharks varies between species, each shark has only a single long-wavelength-sensitive cone type, suggesting that sharks may be cone monochromats and, therefore, potentially colour blind.

Microspectrophotometry of visual pigments and oil droplets in a marine bird, the wedge-tailed shearwater Puffinus pacificus: topographic variations in photoreceptor spectral characteristics

  • 2004
TLDR
It is proposed that the reduction in cone oil droplet pigmentation in retinal areas associated with high visual acuity is an adaptation to compensate for the reduced photon capture ability of the narrower photoreceptors found there.

Visual ecology of the Australian lungfish (Neoceratodus forsteri)

TLDR
The presence of a complex colour vision system based on multiple cone types and intracellular spectral filters in lungfishes suggests that many of the ocular characteristics seen in terrestrial or secondarily aquatic vertebrates may have evolved in shallow water prior to the transition onto land.
