A small tropical freshwater fish with a highly compressed body shaped like a hatchet blade, with large pectoral fins.
Compound of 'hatchet' + 'fish,' referencing the distinctive hatchet-like body shape of these Amazonian fish (family Gasteropelecidae).
Hatchetfish have such an unusual shape that they can achieve powered flight, actually jumping out of water and 'flying' for short distances—their name captures both their appearance and their weird ability.
