“…The visual sys tem of this species, however, is not especially sensitive to those wavelengths (Cohen & Frank 2007), and the function of the luminescence is not known. Nonluminous amphipods will track blue light sources (Land et al 1995), and it is suggested that they use this in hunting for the biolu minescent jellies they parasitize. Although the group that includes Scina and Proscina is not usually thought to be parasitic, examples of associations between Proscina and gelatinous hosts have been found (Gasca et al 2007).…”

Bioluminescence spans all oceanic dimensions and has evolved many times--from bacteria to fish--to powerfully influence behavioral and ecosystem dynamics. New methods and technology have brought great advances in understanding of the molecular basis of bioluminescence, its physiological control, and its significance in marine communities. Novel tools derived from understanding the chemistry of natural light-producing molecules have led to countless valuable applications, culminating recently in a related Nobel Prize. Marine organisms utilize bioluminescence for vital functions ranging from defense to reproduction. To understand these interactions and the distributions of luminous organisms, new instruments and platforms allow observations on individual to oceanographic scales. This review explores recent advances, including the chemical and molecular, phylogenetic and functional, community and oceanographic aspects of bioluminescence.

“…Bioluminescence in most marine bacteria peaks at the wavelength of ∼490 nm (25), which, not surprisingly, is near the wavelength least absorbed in seawater (26). Several zooplankton taxa [e.g., two species of the copepod Pleuromamma (27), hyperiid amphipods (28), and some deep-sea crustaceans (29)] were shown to be sensitive to similar wavelengths. Mesopelagic crustaceans have a single peak of spectral sensitivity at 470-500 nm, presumably exhibiting greater sensitivity to bioluminescence than to downwelling light (30).…”

The benefits of bioluminescence for nonsymbiotic marine bacteria have not been elucidated fully. One of the most commonly cited explanations, proposed more than 30 y ago, is that bioluminescence augments the propagation and dispersal of bacteria by attracting fish to consume the luminous material. This hypothesis, based mostly on the prevalence of luminous bacteria in fish guts, has not been tested experimentally. Here we show that zooplankton that contacts and feeds on the luminescent bacterium Photobacterium leiognathi starts to glow, and demonstrate by video recordings that glowing individuals are highly vulnerable to predation by nocturnal fish. Glowing bacteria thereby are transferred to the nutritious guts of fish and zooplankton, where they survive digestion and gain effective means for growth and dispersal. Using bioluminescence as bait appears to be highly beneficial for marine bacteria, especially in food-deprived environments of the deep sea.B ioluminescence is common in the marine environment, occurring in numerous organisms, from bacteria to invertebrates and fish (1, 2). Bacterial bioluminescence occurs as a continuous glow in the presence of oxygen at cell concentrations exceeding quorum-sensing levels (3-6). Luminous bacteria occur free-living in seawater (7,8), in symbiotic associations with marine organisms (most notably fish and squids; see refs. 7 and 8 and references therein), as saprophytes on suspended organic material such as marine snow (9, 10), as a major component of fecal pellets (11-13), and as parasites on crustaceans (14).Although the adaptive benefits of energetically costly bioluminescence in symbiotic bacteria are well understood (e.g., 7, 15), those benefits in nonsymbiotic bacteria and those living as ectoparasites on zooplankton are less obvious. Several different physiological and biochemical functions of bacterial bioluminescence have been proposed (7,(16)(17)(18)(19)(20), focusing mostly on antioxidative activity, enhanced DNA repair, and UV resistance, although the validity of some of these hypotheses has been questioned (21).An ecological function in propagation and dispersal also has been postulated (6,7,22). According to this hypothesis (hereafter, "bait hypothesis"), the bacteria, by glowing, visually mark the presence of a food particle for fish in order to get into their nutritious guts. So far, this hypothesis was supported by circumstantial evidence showing that luminous bacteria thrive in and survive passage through fish guts (7,12,23,24). Here we propose that the mechanism underlying the bait hypothesis is based on the following steps: (i) Quorum sensing assures that bacterial bioluminescence is a reliable signal of the presence of food aggregates, e.g., marine snow; (ii) zooplankton is attracted to luminous particles and grazes on the bacteria-rich organic matter; (iii) because of its contact with or ingestion of the luminous bacteria, the zooplankton itself becomes glowing; (iv) the glowing zooplankton is detected readily and consumed by fish; (v) once in the ...

“…Although less intensively documented than fishes, crustacean (copepods, amphipods, isopods…) visual system is also reported to have sensitivity shift to bluer wavelength, which aids their bioluminescence detection (Cohen and Forward, 2002;Frank et al, 2012;Marshall et al, 1999;Nishida et al, 2002). In laboratory experiments, Land et al (1995) demonstrated that amphipods where attracted to a blue-light-emitting diode. Unfortunately, and despite these statements, rare studies have investigated the effect of bioluminescence on the ingestion rates of predators (Figure 1, step 2).…”

Abstract. Around thirty species of marine bacteria can emit light, a critical characteristic in the oceanic environment where the major part is deprived of sunlight. In this article, we first review current knowledge on bioluminescent bacteria symbiosis in light organs. Then, focusing on gut-associated bacteria, we highlight that recent works, based on omics methods, confirm previous claims about the prominence of bioluminescent bacterial species in fish guts. Such host-symbiont relationships are relatively well established and represent important knowledge in the bioluminescence field. However, the consequences of bioluminescent bacteria continuously released from light organ and through the digestive tracts to the seawater have been barely taken into account at the ecological and biogeochemical level. For too long neglected, we propose to consider the role of bioluminescent bacteria, and to reconsider the biological carbon pump taking into account the bioluminescence effect (bioluminescence shunt hypothesis). Indeed, it has been shown that marine snow and fecal pellets are often luminous due to microbial colonization, which makes them a visual target. These luminous particles seem preferentially consumed by organisms of higher trophic levels in comparison to non-luminous ones. As a consequence, the sinking rate of consumed particles could be either increased (due to repackaging) or reduced (due to sloppy feeding or coprophagy/coprorhexy) which can imply a major impact on global biological carbon fluxes. Finally, we propose a strategy, at a worldwide scale, relying on recently developed instrumentation and methodological tools to quantify the impact of bioluminescent bacteria in the biological carbon pump.
