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… 
Sensitivity Differences in Fish Offer Near-Infrared Vision as an Adaptable Evolutionary Trait
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.
Zebrafish larvae show negative phototaxis to near-infrared light
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.
Flow Sensing in Air and Water
Aquatic animals of all major phyla have developed sensory systems to perceive water movements, so-called hydrodynamic sensory systems. These water movements, or hydrodynamic stimuli, arise from a
Matched Filter Properties of Infrared Receptors Used for Fire and Heat Detection in Insects
About 25 insect species are attracted by forest fires and thus can be found on freshly burnt areas after fires. In three genera of pyrophilous beetles and one genus of pyrophilous bugs, infrared (IR)
Climbing Perch Anabas testudineus Feeding in the Darkness: Observation in Infrared Light
Abstract A comparative study of the nutrition of climbing perch Anabas testudineus (Bloch, 1792)–fed with granular food with positive buoyancy in the light (~100 lux), in darkness, and under infrared
Lobster in a bottle: a novel technique for observing the predation of juvenile spiny lobster (Jasus edwardsii)
A novel approach for observing attempted predation on live juvenile spiny lobster (Jasus edwardsii) in situ, by presenting the lobster in a transparent container that was lit with infrared light to enable continuous monitoring, even at night, by video recording.
Relative predation risk in two types of habitat for juvenile Australasian spiny lobsters, Jasus edwardsii
Daytime predation attempts were higher in barren compared to kelp habitat; however, there was no difference between the habitats for night time, dawn or dusk observations, when juvenile lobsters are emergent from shelters and vulnerable to predation.
Exploiting common senses: sensory ecology meets wildlife conservation and management
It is illustrated that sensory ecology can facilitate the understanding of mechanistic ecological and physiological explanations underlying particular conservation issues and also can help develop innovative solutions to ameliorate conservation problems.

Visual pigments and the acquisition of visual information.
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.
Effects of Degraded Optical Conditions on Behavioural Responses to Alarm Cues in a Freshwater Fish
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.
The Adaptation of Visual Pigments to the Photic Environment
In 1936 Clarke wrote: “These results [clear ocean water selectively transmits blue light] raise the question of the possibility of a shift in sensitivity of the eyes of a deep water fish towards the
Color signaling in conspicuous red sticklebacks: do ultraviolet signals surpass others?
First experimental evidence that the UV wave band clearly outranks at least one other part of an animal's visible spectrum (SW-) in the context of communication is reported.

The visibility of 350 °C black-body radiation by the shrimp Rimicaris exoculata and man
Physical calculations presented here indicate that the shrimp could see the black-body radiation of the 350 °C vents, even though these sources are practically invisible to the human eye.
Far Red Bioluminescence from Two Deep-Sea Fishes
Spectral measurements of red bioluminescence were obtained from the deep-sea stomiatoid fishes Aristostomias scintillans and Malacosteus niger, which have postorbital light organs that emit blue luminescence with maxima between 470 and 480 nanometers.
Activation of Visual Pigments by Light and Heat
Using a quantitative relation between a pigment’s photoactivation energy and its peak-absorption wavelength, λmax, it is reported here that the relative noise of diverse pigments with multi–vibrational-mode thermal statistics strongly suggests that pigment noise arises from canonical isomerization.
