Boto  (Inia geoffrensis)

Although the most widespread of the river dolphins, botos are threatened by the continued development of the river systems in which they are found (8). Hydroelectric or irrigation schemes that dam rivers act to isolate dolphins in smaller sections of their habitat. These dolphins were previously associated with bad spirits which has perhaps protected them from persecution (7). However, they are now coming into increased conflict with local fisherman who may view the species as competition (8). Dolphins are also caught or injured accidentally during the fishing process; either as bycatch in nets or through collisions with boats and motors (8).

The boto is fully protected by law in both Brazil and Bolivia and is partially protected in areas of Peru, Venezuela and Colombia (4). It is found within the Amazon River Global 200 Ecoregion, which is receiving some degree of international protection and recognition (7). These bizarre-looking pink dolphins have attracted a lot of attention and now support a tourist trade (5); perhaps this interest will be sufficient to preserve the future of this mysterious river dweller.
