Lanternfish

The Lanternfish

The lanternfish, also known as Symbolophorus barnardi, is a deep-water fish that gets its name from its ability to produce light. The light is produced by tiny organs known as photophores. A chemical reaction inside the photophore gives off light in a process known as bioluminescence. It is the same process used by fireflies and is similar to the chemical reaction inside those green light sticks. The photophores are located on the head, underside, and tail of the lanternfish. It is believed that these light organs may be used to attract other small fish on which the lanternfish feeds. They may also be used to signal other lanternfish during mating. Lanternfish grow to a length of about 6 inches. They spend the day in the deep ocean but come close to the surface at night in search of food. Lanternfish are found in all of the world oceans at depths ranging from 1200 to 3000 feet.
