Photophore

a light-emitting organ found in certain animals, such as deep-sea fishes and cephalopods, which is used for communication, camouflage, or attracting prey or mates

What is a "photophore"?

A photophore is a specialized light-producing organ found in certain organisms, particularly deep-sea creatures. It is typically composed of cells containing bioluminescent chemicals that can emit light through a biochemical reaction. Photophores serve a variety of functions, including attracting prey, luring mates, and camouflage. These light-emitting organs are strategically located on the body of the organism, often along the ventral side or around the head, and can produce a range of colors and patterns. The ability to generate light in the darkness of the deep sea is crucial for communication, hunting, and defense. Some species have elaborate arrangements of photophores, forming intricate patterns or rows that create mesmerizing light displays. The study of photophores and bioluminescence provides valuable insights into the fascinating adaptations of organisms to their deep-sea environments.

Examples

1. But the ninja lanternshark is very different: it has fewer photophores and it has jet-black scales, which make it a great stealth hunter.

2. It has bioluminescent organs called photophores that produce flashes of light.

3. Normally a fish's silhouette against the sky gives it away, but these photophores make the hatchet fish blend in.

4. Their skin contains bioluminescent organs called photophores, which give the shark an eerie green glow.
