hatchetfish
Bioluminescent compressed swimmer
Hatchetfish are small fish with thin, deep bodies shaped like a hatchet blade.
Freshwater hatchetfish are popular aquarium fish native to South America, known for their ability to leap from the water.
Deep-sea hatchetfish live in ocean depths, their bodies equipped with light-producing organs that help them evade predators in the darkness.
