Tooninas

Tooninas are a genus of river dolphins found in South America. The genus currently contains only one recognized species, the Amazon river dolphin, also known as the boto. These toothed whales inhabit the freshwater river systems of the Amazon and Orinoco basins.

Tooninas are characterized by their distinct pinkish coloration, which becomes more pronounced in adult males. They possess a flexible neck, allowing for greater maneuverability in the complex river environments. Unlike many other dolphin species, Tooninas have relatively small eyes, which is likely an adaptation to their murky water habitats where vision is limited. They are known for their long snouts and prominent foreheads.

The diet of Tooninas primarily consists of fish, but they have also been observed consuming crustaceans and other small aquatic animals. They are generally solitary or found in small groups. Their behavior and social structure are not as extensively studied as some of their marine counterparts.

Conservation status for the Tooninas genus and its sole species is a concern. Threats include habitat degradation, pollution, dam construction, and entanglement in fishing gear. These factors have led to declining populations in some areas, making ongoing research and conservation efforts crucial for their survival.
