Pink River Dolphin

The Amazon River Dolphin (Inia geoffrensis), also known as Pink River Dolphin, is a species of toothed whale and the largest species of river dolphins. Adults acquire a pink color, more prominent in males, giving it its nickname "pink river dolphin". Like other toothed whales, they have a melon, an organ that is used for biosonar. The dorsal fin, although short in height, is regarded as long, and the pectoral fins are also large. The fin size allows for improved maneuverability when navigating flooded forests and capturing prey.
They feed on different species of fish, such as croakers, catfish, tetras, and piranhas. They also consume other animals such as river turtles and freshwater crabs.
