These fish, known for their ability to glow in the dark, are among the most abundant vertebrates on the planet. But despite their numbers, they remain largely unseen by human eyes. ● What Are Lanternfish? Lanternfish belong to the family Myctophidae, a group of deep-sea fish found in oceans worldwide.
