by The Amazon leaffish (Monocirrhus polyacanthus), or South American leaffish, is a species of fish belonging to the family Polycentridae.
It is found in the Amazon basin in Bolivia, Brazil, Colombia, Peru and Venezuela, where it inhabits edges of rivers and lakes, and streams.
It is generally a low-density species that lives in slow-moving or essentially stagnant waters in areas with plant debris.
The Amazon leaffish reaches a maximum standard length of 8 cm (3.1 in),[1][3] and a total length of 10 cm (3.9 in).
As suggested by its common name, it closely resembles a dead leaf.
The flattened body and filament at the tip of the lower jaw (resembling a stalk) further enhances its similarity to a leaf.
It is gray-brown, but can change its color to some extent.
There is no lateral line and its large mouth can be protracted to as much as 60% of the head length.
