The Colossoma macropomum, commonly called the tambaqui, is a large freshwater fish native to the rivers of the Amazon and Orinoco basins in South America. It can grow up to a metre long and weigh over 30 kilograms, making it one of the biggest fish in its habitat. Tambaqui are known for their strong, rounded teeth, which allow them to crush seeds, nuts, and fruits that fall into the water from the rainforest canopy — a rare skill among fish. They also eat small fish and invertebrates, making them omnivorous.

Tambaqui play an important role in the rainforest ecosystem by helping to disperse seeds, which supports the growth of new trees. These fish are excellent swimmers, navigating flooded forests with ease, and they often travel in schools for safety and social interaction.
