Description

Buffon's river garfish is a halfbeak (Zenarchopteridae) from the Indo-West Pacific. The species has a slender, silvery body with a short upper jaw and a strongly elongated, beak-like lower jaw. It keeps at the water surface in coastal waters, estuaries and the lower reaches of rivers. It feeds mainly on terrestrial insects fallen onto the water. Fertilisation is presumably internal, but the species lays eggs. The species is harmless to humans.
