Just under 3 meters (9.8 ft.) in length, the boto - also known as the Amazon River dolphin or bufeo colorado - is the largest member of the river dolphin family (Platanistidae). It inhabits most of the Amazon and Orinoco River basins: the largest river system in the world. The first part of its scientific name, Inia, is what the Guarayo Indians of Bolivia call this species. The species name, geoffrensis comes from Geoffrey St. Hilaire (1772-1850), a prominent French professor of natural history who was instrumental in procuring the first specimens of the boto.
|Most populations of this dolphin are believed to be in good condition. However they are especially vulnerable to habitat degradation. A number of factors may affect these dolphins.
