Detailed explanation-1: -Or, more likely, you’re a marine animal. A whopping 76 percent of ocean animals are bioluminescent, which means they produce their own light through a series of chemical reactions or host bacteria that do.

Detailed explanation-2: -Why do organisms use bioluminescence? In the deep sea where little sunlight penetrates, deep-sea animals have adapted to use light to their benefit. They can turn it on and off, for a variety of both offensive and defensive strategies ranging from avoiding predators to finding their next meal-or even a mate.

Detailed explanation-3: -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-4: -Bioluminescence is the result of a chemical process named “chemiluminescence”, which is when light is produced due to a chemical reaction. Two chemicals interact with each other, yielding an unstable high energy compound. This unstable energy is then released as light to reach a stable state.
