Details

Habitat

It lives in deep channels, confluences, and pools of the Ganges, Brahmaputra, and Meghna systems. Main habitat types in this guide are freshwater.

Appearance

Typical length 200-260 cm, weight 70 kg-90 kg. A long beak, tiny eyes, stocky body, and flexible neck are distinctive.

Behavior

It is active in repeated bouts across day and night and usually solitary. It surfaces alone or in small numbers and searches muddy channels with sound.

Feeding

It is carnivorous. Fish, shrimp, and bottom animals are detected and seized with the long beak.
