Many animal species are able to perceive light wavelengths beyond those visible to humans. While numerous species are additionally sensitive to short wavelengths (UV), long wavelengths such as the near-infrared spectrum (NIR) are supposed to be unsuitable for visual perception. Here, we experimentally show that under exclusive NIR illumination, the cichlid fish Pelvicachromis taeniatus displays a clear foraging response towards NIR reflecting prey. Additional control experiments without prey… Expand

Sensitivity Differences in Fish Offer Near-Infrared Vision as an Adaptable Evolutionary Trait
TLDR
A clear correlation between NIR sensation thresholds and availability of NIR in the natural habitats is revealed, suggesting that NIR vision, as an integral part of the whole spectrum of visual abilities, can serve as an evolutionarily adaptable trait in fish. Expand
Zebrafish larvae show negative phototaxis to near-infrared light
TLDR
It is demonstrated that zebrafish larvae are able to perceive NIR at 860 nm, which is almost identical to the most commonly used light source in commercial screening systems to create a dark environment. Expand
Can species‐specific prey responses to chemical cues explain prey susceptibility to predation?
TLDR
It is suggested that chemical cue perception might be behind community data change and it is encouraged to collect more community data of tested prey species before and after European catfish introduction to test the hypothesis. Expand
Sensory basis for detection of benthic prey in two Lake Malawi cichlids.
TLDR
Investigating how functionally distinctive differences in sensory morphology are correlated with feeding behavior in the laboratory and determining the role of sensory systems in feeding ecology will provide insights into how sensory capabilities may contribute to trophic niche segregation. Expand

Visual pigments and environmental light
TLDR
There is evidence based on immunocytochemistry and action spectra that at least some of the skin and pineal receptors contain visual pigments, but like those of the rods, these do not match the spectral quality of the environmental light. Expand

    Visual pigments and the acquisition of visual information.
    TLDR
    Significant differences between the cone sets of animals living within the same environment and colour vision polymorphism within a species suggest that visual tasks critical to survival or breeding success require particular visual pigment sets. Expand

    The increased reliance on chemical cues indicates that crucian carp can compensate for the reduced information content from vision in waters where optical conditions are degraded. Expand

    Color signaling in conspicuous red sticklebacks: do ultraviolet signals surpass others?

    Non-rod, non-cone photoreception in the vertebrates
    TLDR
    This review hopes to convince the more casual reader that there is much more to vertebrate photoreceptors than the study of retinal rods and cones, and that inner retinal photoreception will be a feature of all vertebrates. Expand

    TLDR
    A host of detailed information has become available on the widespread distribution of UV receptors in different species - from insects to mammals - and the important functions they seem to play in navigation, foraging, intraspecies communication and the control of circadian rhythms. Expand

    TLDR
    A simple equation is presented as a generic description for the alpha-band of mammalian photoreceptor spectral sensitivity curves, and it seem likely that the equation may be equally applicable to retinal1-based pigments in other species. Expand
