River systems of Amazon and Orinoco
They enter lakes during periods of high water. They may have a limited home range, but the size of that area is unknown.
Social system/Group size
Usually seen in groups of 1 - 6, but sometimes up to 15 individuals in rich feeding grounds.
They mainly suffer from entanglement in fishing gear, habitat degradation and pollution.
Some fishermen believe the tucuxi to be a sacred animal that brings the bodies of the drowned back to shore.
