Detailed explanation-1: -Several deep-sea fish, such as anglerfish and viperfish, use bioluminescence as a lure to attract prey. The dangling appendage that extends from the head of the anglerfish has a light organ at the end which attracts small animals to within striking distance.

Detailed explanation-2: -According to NOAA, scientists estimate that bioluminescence exists in 90 percent of the animals living in the open ocean, in waters below 500 m (1, 640 ft). It’s a trait that has evolved in a variety of organisms-a small fraction of which are in this slideshow. Bioluminescence has inspired scientists and artists alike.

Detailed explanation-3: -One of the species, the kitefin shark, grows to a length of nearly six feet, making it the largest known bioluminescent vertebrate. Giant squid, which get much bigger, are also known to produce light.

Detailed explanation-4: -Marine creatures rely on bioluminescence for communication, finding prey, camouflage, and more. It’s so important, in fact, that the trait has evolved 27 times among ray-finned fishes, a huge group that makes up half of all vertebrate species alive today.
