Description

The highwaterman catfish is a catfish from the Amazon and Orinoco basins and coastal rivers of the Guianas in South America. It grows to about 58 cm and has an elongate, silvery body with low-set eyes and long barbels. Notably it lacks jaw teeth but uses numerous long gill rakers as a sieve. It lives in schools just below the water surface over muddy bottoms and filters zooplankton such as water fleas and copepods from the water. It is a food fish; females lay tens of thousands of eggs. The IUCN assesses the species as Least Concern (LC).
