The common hatchetfish or river hatchetfish, Gasteropelecus sternicla, is a tropical fish belonging to the freshwater hatchetfish family (Gasteropelecidae). Originating in the South America in the Peruvian and middle Amazon, the Guianas and Venezuela, it grows to about 2.5 inches (6.5 cm). The fish gets its name from its relatively large protruding belly which resembles a hatchet. Hatchetfish will often jump out of the water when alarmed, propelled by their large, winglike pectoral fins. They may also jump to catch small aerial insects.
