Lamp fish are creatures found in the deep ocean. They have large light-emitting organs on their bodies, as well as larger ones on their tails. These organs are called photophores and produce bioluminescence, or glowing light in the dark. Photophores are made of special proteins that produce light when activated by a chemical reaction.
These creatures have a unique pattern of photophores that help male lanternfish to locate females in the dark. The female lays several eggs in the water column. The larvae hatch with a few photophores, and the number increases as they grow. These fish will reach a length of 13 cm (5 inches) when fully grown.
