Description

The South American catfish (jundia) is a scaleless bottom catfish of the family Heptapteridae reaching about 61 cm. The elongate, brown-grey body has three pairs of long barbels around the broad mouth, an adipose fin and stout, serrated spines in the pectoral and dorsal fins. The species comes from the fresh water of Central and South America and lives on often soft bottoms of rivers, lakes and creeks. Mainly at night it probes the bottom with its barbels for insects, crustaceans, small fish, worms and plant matter. With its tasty, low-bone flesh it is an important food and aquaculture fish in South America; when handling, the sharp fin spines call for care.
