An object appears red to the eye because it reflects red light and absorbs other colours. So the only colour reaching the eye is red. Blue is the only colour of light available at depth underwater, so it is the only colour that can be reflected back to the eye, and everything has a blue tinge under water.
In marine coastal habitats, about 2.5% of organisms are estimated to be bioluminescent, whereas in pelagic habitats in the eastern Pacific, about 76% of the main taxa of deep-sea animals have been found to be capable of producing light. [39] More than 700 animal genera have been recorded with light-producing species. [40] Most marine light ...
Deep-sea organisms generally inhabit bathypelagic (1-4 km, 0.6-2.5 mi deep) and abyssopelagic (4-6 km, 2.5-3.7 mi deep) zones. However, characteristics of deep-sea organisms, such as bioluminescence can be seen in the mesopelagic (200-1,000 m, 650-3,300 ft deep) zone as well. The mesopelagic zone is the disphotic zone, meaning light there is ...
Anglerfish can wiggle the esca to make it resemble a prey animal, which lures the anglerfish's prey close enough for the anglerfish to devour them whole. [31] Some deep-sea anglerfish of the bathypelagic zone also emit light from their esca to attract prey. [32]
The sea cucumber, like other bioluminescent animals, is able to emit light. It uses this effect as an alarm to expose its self and potential predators in times of an attack.
Like other hydrozoans, some siphonophores emit light to attract and attack prey. While many sea animals produce blue and green bioluminescence, a siphonophore in the genus Erenna was only the second life form found to produce a red light (the first one being the scaleless dragonfish Chirostomias pliopterus).
