Description

The Amazon leaffish is a leaffish (Polycentridae) from South America. The species has a deep, laterally compressed, brown-mottled body and a chin barbel, making it resemble a dead, floating leaf. With this camouflage it stalks prey unseen and then shoots out its enormously protrusible mouth to suck up small fishes in one gulp. It lives in quiet, shaded parts of rivers and streams. The species is harmless to humans.
