The silver hatchetfish (Gasteropelecus levis) is a freshwater hatchetfish found only in the lower Amazon basin in the state of Pará, Brazil. It spends almost all of its time at or just below the surface, and can leap from the water and glide for several metres to catch flying insects or escape predators. It lives in open water of larger igarapés, streams and floodplain lakes.
