Some fish make their own light!
• A photophore is a light-emitting organ. • It can be simple. • It can be fancy (shutters, color filters). • The light can be produced from
1) Digesting certain foods 2) Special cells called photocytes 3) Light-producing bacteria that are grown in the fish (symbiotic)
