Bioluminescence is a fascinating phenomenon and can be found in many different organisms including fish. It has been suggested that bioluminescence is used for example for defense, prey attraction, and for intraspecific communication to attract for example sexual partners. The flashlight fish, Anomalops katoptron (A. katoptron), is a nocturnal fish that produces bioluminescence and lives in shallow waters, which makes it ideal for laboratory studies. In order to understand A. katoptron’s…

Social signaling via bioluminescent blinks determines nearest neighbor distance in schools of flashlight fish Anomalops katoptron
Blink frequencies are modified by changes in the occlusion time and are increased from day to night and during avoidance behavior, while group cohesion is higher with increasing blink frequencies, suggesting that specific blink patterns in schooling flashlight fish A. katoptron define nearest neighbor distance and determine intraspecific communication.
Social signaling via bioluminescent blinks drives schooling behavior in the flashlight fish Anomalops katoptron
It is suggested that visually transmitted information via specific blink patterns determine intraspecific communication and group cohesion in schooling A. katoptron.
Analysis of the Territorial Aggressive Behavior of the Bioluminescent Flashlight Fish Photoblepharon steinitzi in the Red Sea
The data show that the intensity of displayed aggression potential in P. steinitzi depends on the signal properties of the intraspecific intruder, and a constant glowing light organ dummy or a fish dummy simulating an intruder increases the aggression level in the fish.
Visual system diversity in coral reef fishes.
This review examines the interplay between retinal morphology and light environment across a number of reef fish species, but mainly focusses on visual adaptations at the molecular level (i.e. visual pigment structure) and focuses on the seven reef fish families most comprehensively studied to date.
Reviews and syntheses: Bacterial bioluminescence – ecology and impact in the biological carbon pump
Around 30 species of marine bacteria can emit light, a critical characteristic in the oceanic environment is mostly deprived of sunlight. In this article, we first review current knowledge on
Reviews and syntheses: Bacterial bioluminescence – ecology and impact in the biological carbon pump
This article first reviews current knowledge on bioluminescent bacteria symbiosis in light organs, then focuses on gut-associated bacteria, and proposes a strategy, at a worldwide scale, relying on recently developed instrumentation and methodological tools to quantify the impact of biolumscent bacteria in the biological carbon pump.
Effects of different light spectra on embryo development and the performance of newly hatched turbot (Scophthalmus maximus) larvae.
The results of the present study indicate that LDO and LDF should be used for embryo incubation and newly hatched larvae when rearing turbot, providing a theoretical basis for optimizing the incubation light environment for fertilized turbot eggs, promoting immunity and reducing stress responses in Newly hatched larvae.
Influence of light spectra on the performance of juvenile turbot (Scophthalmus maximus)
Overall, the results of the current study suggested that light spectrum had a significant effect on the performance of juvenile turbot, with growth retardation, together with decreased antioxidative activity and pathogen resistance observed in the red and orange groups.


The Flashlight Fish Anomalops katoptron Uses Bioluminescent Light to Detect Prey in the Dark
These experiments performed in a coral reef tank show that Anomalops katoptron use bioluminescent illumination to detect planktonic prey and that the blink frequency of A. kat optron light organs follow an exogenous control by the ambient light.
Light for All Reasons: Versatility in the Behavioral Repertoire of the Flashlight Fish
The flashlight fish, Photoblepharon, possesses headlight-like luminous organs situated in the orbit just below the eyes, and it is postulated that the bioluminescence is used by the fish to assist in obtaining prey, to deter or escape predators, and for intraspecific communication.
Vision in lanternfish (Myctophidae): adaptations for viewing bioluminescence in the deep sea
The sensitivity hypothesis seeks to explain the correlation between the wavelength of visual pigment absorption maxima (lambda(max)) and habitat type in fish and other marine animals in terms of the
The visual pigments of a deep-sea teleost, the pearl eye Scopelarchus analis
This is the first time that the presence of a cone pigment in a deep-sea fish has been confirmed by molecular analysis and the values of the RH1A and RH1B pigments at 486 and 479 nm have been determined by in vitro expression of the recombinant opsins and show the typical short-wave shifts of fish that live in deep water compared to surface dwellers.
In search of the visual pigment template
Absorbance spectra were recorded by microspectrophotometry from 39 different rod and cone types representing amphibians, reptiles, and fishes, with A1- or A2-based visual pigments and λmax ranging
Melanopsin Tristability for Sustained and Broadband Phototransduction
By broadening the tuning of ipRGCs in both temporal and chromatic domains, melanopsin tristability produces signal integration for physiology and behavior.
Seeing in the deep-sea: visual adaptations in lanternfishes
The current body of knowledge on the visual system of one of the most abundant and intensely studied groups of mesopelagic fishes: the lanternfish (Myctophidae) is reviewed to discuss how the plasticity, performance and novelty of its visual adaptations, compared with other deep-sea fishes, might have contributed to the diversity and abundance of this family.
The significance of spectral position in the rhodopsins of tropical marine fishes.
The behavioral patterns of reef fishes make clear the relationships between underwater light and the visual pigments, and crepuscular predators obtain a visual advantage by having moderate numbers of very large cones, which provide adequate sensitivity and sufficient resolution for motion detection.
Molecular Basis of Spectral Tuning in the Newt Short Wavelength Sensitive Visual Pigment
The seven amino acid residues that were replaced are the major cause of the red shift of the newt SWS2 pigment's spectrum.

To better understand the molecular and functional adaptations of visual pigments, it is necessary to identify all critical amino acid replacements that are involved in the spectral tuning and elucidate the effects of their interactions on the spectral shifts.
