Some species of cephalopod, such as the eye-flash squid and the firefly squid, produce light in photophores on their undersides to match the background. [2] Bioluminescence is common among marine animals, so counter-illumination may be widespread, though light has other functions, including attracting prey and signaling. [5] [6]
Noctiluca scintillans, a bioluminescent dinoflagellate. Bioluminescence is the production of light by living organisms. This list of bioluminescent organisms is organized by the environment, covering terrestrial, marine, and microorganisms.
The bioluminescence used for counter-illumination can be either autogenic (produced by the animal itself, as in pelagic cephalopods such as Vampyroteuthis, Stauroteuthis, and pelagic octopuses in the Bolitaenidae [10]) or bacteriogenic (produced by bacterial symbionts).
Like many creatures living in the deep ocean, the strawberry squid can light itself up using bioluminescence. The squid floats along the water upside down with one eye aimed at the ocean floor and ...
The firefly squid inhabits the waters off the coast of Japan. [13] [14] The depth at which these squids can be found varies (300–400 m or 1,000–1,300 ft during the day, and 20–60 m or 70–200 ft during the night) over the course of a day, [14] as they are one of the several species of squid that participates in diel vertical migration.
Photo shot through a polarizing filter of a Cranchiidae sp from the Operation Deep Scope Expedition 2004. This squid, about four-inches across, uses transparency to hide from potential predators.
Margaret McFall-Ngai (born 1951) is an American animal physiologist and biochemist [1] best-known for her work related to the symbiotic relationship between Hawaiian bobtail squid, Euprymna scolopes and bioluminescent bacteria, Vibrio fischeri. Her research helped expand the microbiology field, primarily focused on pathogenicity and ...
