The flashlight fish are a family, the Anomalopidae, of beryciform fish. Some unrelated fish with similar features are also called flashlight fish. Notable among these are the deepsea lanternfish.
Flashlight fish live in tropical waters across the world. Some species move to shallow waters or coral during the night, but otherwise, they are exclusively deep water fish. They are typically about 14 cm (5.5 in) in adult length, although some species reach twice this size. They feed on small crustaceans. Flashlight fish are named for their large bioluminescent organs. These are located beneath the eyes and contain luminous bacteria. Two methods are used by different species for controlling light emission, either a shutter-like lid is raised over the organ or the organ is turned downward into a pouch. The light is used for predator avoidance, to attract prey, and for communication. Evolution doesn't plan so it isn't the answer here. God is so creative and only He could have created something like this. ~Jason White, Biblical Creation
Bioluminescence is an extraordinary capability utilized by many insects, plants, bacteria, and underwater creatures. Their luminescence can function as a form of communication or aid in functions such as hunting or mating. Bioluminescence occurs as result of a chemical process including two molecules, luciferin and luciferase. These two components can be represented differently in different luminescent creatures; i.e. marine animals versus insects. Due to its unique abilities, bioluminescence has been widely recognized by the scientific community. Scientists have now found ways to treat infections, bacteria, and even cancer. This miraculous process, which many evolutionists would claim to be a masterful result of evolution, in fact strongly supports the concept of a creator. There is no conceivable how or why bioluminescence would occur spontaneously or through a long drawn-out process over millions of years. Therefore, it strongly supports the words of the Bible, describing how a powerful God created the universe and all creatures, plants, etc. therein. http://creationwiki.org/Bioluminescence
