Most deep-sea fish have visual pigments that are most sensitive to wavelengths around 460-490 nm, the intensity maxima of both conventional blue bioluminescence and dim residual sunlight. The predatory deep-sea dragon fish Malacosteus niger, the closely related Aristostomias sp. and Pachystomias microdon can, in addition to blue bioluminescence, also emit far-red light from suborbital photophores, which is invisible to other deep-sea animals. Whereas Aristostomias sp. enhances its long… Expand
Long-wave sensitivity in deep-sea stomiid dragonfish with far-red bioluminescence: evidence for a dietary origin of the chlorophyll-derived retinal photosensitizer of Malacosteus niger.
TLDR
Three genera of deep-sea loose-jawed dragonfish are sensitive in this part of the spectrum, to which all other animals of the deep sea are blind, potentially affording them a private waveband for illuminating prey and for interspecific communication that is immune from detection by predators and prey.

Enhanced retinal longwave sensitivity using a chlorophyll-derived photosensitiser in Malacosteus niger, a deep-sea dragon fish with far red bioluminescence
TLDR
To compensate for its apparently reduced longwave sensitivity compared to related species, the outer segments of M. niger contain additional pigments, which are identified as a mixture of defarnesylated and demetallated derivatives of bacteriochlorophylls c and d that are used as a photosensitiser to enhance its sensitivity to longwave radiation. Expand
Chlorophyll derivatives enhance invertebrate red-light and ultraviolet phototaxis
TLDR
The findings show that the interaction between chlorophyll derivatives and opsins virtually concerns the vast majority of bilaterian animals, and also occurs in visual systems based on rhabdomeric (rather than ciliary) opsins. Expand
Spectral Sensitivity Tuning in the Deep-Sea
Deep-sea fishes can be exposed to both dim residual sunlight and bioluminescence, both of which are usually most intense in the blue/green part of the spectrum. Not surprisingly, therefore, the vastExpand
The Ecology of Teleost Fish Visual Pigments: a Good Example of Sensory Adaptation to the Environment?
TLDR
The aquatic environment offers a natural laboratory for the study of visual ecology, as many fish probably modify their visual pigment complement, either during development or seasonally, as they change factors such as their feeding habits, geographical location, depth of habitat and photic environment. Expand
Red fluorescence in reef fish: A novel signalling mechanism?
TLDR
Red fluorescence is widespread among marine fishes and many features indicate that it is used as a private communication mechanism in small, benthic, pair- or group-living fishes, many of these species show quite cryptic colouration in other parts of the visible spectrum. Expand
An accessory chromophore in red vision
TLDR
It is shown that living rods extracted from a salamander can also accumulate an exogenous chlorophyll derivative, chlorin e6, that renders them as sensitive to red light as they are to green. Expand
Localisation and origin of the bacteriochlorophyll-derived photosensitizer in the retina of the deep-sea dragon fish Malacosteus niger
TLDR
Instead up-regulated Malacosteus genes were associated with photosensitivity and may relate to its unique visual ecology and the chlorophyll-based visual system, and it is suggested that the unusual longwave-reflecting, astaxanthin-based, tapetum of Malacosta may protect the retina from the potential cytotoxicity of such a system.

Diversity and Ecological Correlates of Red Fluorescence in Marine Fishes
TLDR
The largest data set of red fluorescence in fishes to date is collected and analyzed, consisting of confirmed cases in 272 primarily diurnal fish species from 49 out of 90 surveyed fish families and 12 out of 21 surveyed fish orders, contrasted to 393 fish species with confirmed absence ofred fluorescence.

Using red light for in situ observations of deep-sea fishes
Abstract Observations of animals in the deep ocean typically require the use of bright lights that can damage eyes and disrupt normal behaviors. Although the use of infrared light is an effectiveExpand
