Eye features and retinal photoreceptors of the nocturnal aardvark (Orycteropus afer, Tubulidentata).
PLoS ONEThe nocturnal aardvark Orycteropus afer is the only extant species in the mammalian order Tubulidentata. Previous studies have claimed that it has an all-rod retina.

Novel rodent models for macular research [PDF]
, 2010 Background: Many disabling human retinal disorders involve the central retina, particularly the macula. However, the commonly used rodent models in research, mouse and rat, do not possess a macula.

Insect Science, Volume 33, Issue 1, Page 325-335, February 2026.Jewel beetles can discriminate leaf feeding sites and bark oviposition sites based upon the opponent comparison of their blue, green, and red photoreceptor signals. Through this mechanism, green traps resemble leaves, and purple traps resemble bark, explaining their different attractiveness to males and females.

The Formation and Renewal of Photoreceptor Outer Segments
CellsThe visual system is essential for humans to perceive the environment. In the retina, rod and cone photoreceptor neurons are the initial sites where vision forms.

Visual pigments, ocular filters and the evolution of snake vision [PDF]
, 2016 Much of what is known about the molecular evolution of vertebrate vision comes from studies of mammals, birds and fish. Reptiles (especially snakes) have barely been sampled in previous studies despite their exceptional diversity of retinal photoreceptor

Aging Cell, Volume 25, Issue 2, February 2026.Blue light causes retinal injury by inducing excessive mitochondrial fission and epithelial‐mesenchymal transition in retinal pigment epithelial cells. Therapeutic targeting of Drp1 rescues this damage, restoring mitochondrial homeostasis and retinal integrity.

Switch in rod opsin gene expression in the European eel, Anguilla anguilla (L.)
Proceedings of the Royal Society of London. Series B: Biological Sciences, 1998 The rod photoreceptors of the European eel, Anguilla anguilla (L.), alter their wavelength of maximum sensitivity (lambda max) from c.a. 523 nm to c.a. 482 nm at maturation, a switch involving the synthesis of a new visual pigment protein (opsin) that is inserted into the outer segments of existing rods.

Headache: The Journal of Head and Face Pain, Volume 66, Issue 1, Page 132-143, January 2026.Abstract Objective The aim of this study was to determine the photoreceptor basis of light avoidance in mice and assess the effect of CGRP sensitization on this behavior. Background Prior studies have suggested that photophobia is mediated by a subset of retinal ganglion cells (RGCs) that contain melanopsin, making them intrinsically photosensitive ...

Functional characterization of the rod visual pigment of the echidna (Tachyglossus aculeatus), a basal mammal [PDF]
, 2017 Monotremes are the most basal egg-laying mammals comprised of two extant genera, which are largely nocturnal. Visual pigments, the first step in the sensory transduction cascade in photoreceptors of the eye, have been examined in a variety of vertebrates,

A perspective on color vision in platyrrhine monkeys [PDF]
, 1960 Studies carried out over the past two decades show that many platyrrhine (New World) monkeys have polymorphic color vision. This condition results from the sorting of allelic versions of X-chromosome cone opsin genes at a single gene site, yielding a ...
