The anglerfish are fish of the teleost order Lophiiformes (/ ˌ l ɒ f i ɪ ˈ f ɔːr m iː z /). [1] They are bony fish named for their characteristic mode of predation, in which a modified luminescent fin ray (the esca or illicium) acts as a lure for other fish.
Females use the bulbous esca as a bioluminescent lure to attract prey. [12] The bioluminescence of M. johnsonii is caused by symbiont Enterovibrio escacola bacteria on the esca. [13] [14] It was originally thought that E. escacola was an obligate symbiont of its host because its genome was reduced about 50% compared to an average free-living ...
The same species washed up on the state park’s shore two years ago, officials said.
Bioluminescence in fish began at least by the Cretaceous period. About 1,500 fish species are known to be bioluminescent; the capability evolved independently at least 27 times. Of these, 17 involved the taking up of bioluminous bacteria from the surrounding water while in the others, the intrinsic light evolved through chemical synthesis.

Luminescent bacteria emit light as the result of a chemical reaction during which chemical energy is converted to light energy. Luminescent bacteria exist as symbiotic organisms carried within a larger organism, such as many deep sea organisms, including the Lantern Fish, the Angler fish, certain jellyfish, certain clams and the Gulper eel.
The deep-sea angler fish in particular has a long fishing-rod-like adaptation protruding from its face, on the end of which is a bioluminescent piece of skin that wriggles like a worm to lure its prey. Some must consume other fish that are the same size or larger than them and they need adaptations to help digest them efficiently.
Many of the animals in the aphotic zone are bioluminescent, meaning they can produce their light. Bioluminescence can be used both for navigation and luring small animals into their jaws. An excellent example of this is the angler fish, as it has a light lure protruding in front of its mouth from a unique appendage on its head which provides ...
