A new study in the Caribbean Sea found that bioflourescence in fish isn’t so rare after all. So we knew about the glowing corals and jellyfish and even parrots, but glowing fish really wasn’t a big one. Researchers were inspired by a green eel fluorescing off of Little Cayman Island and that got them to research more. They used specific lighting to mimic the ocean’s light and a special camera that can capture the fishes fluorescent light. With bioflourescense, the animal absorbs light, converts it, and sends it out a different color. The team identified over 180 species of bioflourescent fish, and that these fish have yellow filter in the eyes that help them see normally invisible fluorescent displays. Not only is this glowing protein beneficial to the species for communication and protection, but it could be useful for humans in a wide variety of scientific uses!
