Many living organisms know how to glow - due to internal resources. This ability is called bioluminescence. Residents of the middle strip are mostly familiar to fireflies, but they are most often found in fish: it is not surprising, because many of them live in total darkness.
Recently, scientists have found out: 80 percent of ray-finned fish independently illuminate the world around them, and over 150 million years of evolution this ability has arisen independently at least 29 times! Lenta.ru shows the most unusual bioluminescent fish.
