Frequently occurs in counter current zones of principal rivers and creeks. Feeds mainly on fish but also on other animals that fall into the water like small terrestrial invertebrates. Is active at dusk and at night. Reproduction takes place at the onset of the rainy season from December to March. Depending on the size, the female can carry around 6,000 to 60,000 eggs (Ref. 12225). Known for the quality of its flesh (Ref. 27188).
