The Dusky Narrow Hatchetfish is native to river channels of much of the Amazon Basin, including in Ecuador, Bolivia, Peru, Venezuela and Brazil. It grows to 18cm long. The hatchet shape with deep keel has powerful chest muscles which allow the fish to leap well out of the water and glide several metres, both to evade predators and also, especially in flooded forests, to pick fruit, seeds and insects/spiders from the trees or to catch insects in flight. It also feeds on those which fall to the water surface. It often swims in shoals.
