There are several small, freshwater hatchetfish native to South Ammerica. The hatchet shape with oversized keel
has powerful chest muscles which allow the fish to leap well out of the water and glide a few metres to escape predators. The Spotted
Hatchetfish, also called Spotted Silver Hatchetfish, is native to waterways on the Pacific sides of Panama and Colombia (and maybe Ecuador).
A shoaling fish, it grows to some 9cm long (larger than the "Giant" Hatchetfish). Head on, it is very narrow.
It feeds mainly on small insects that fall to the water surface.
