The pink and mottled pink-gray river dolphin is poorly studied, and poorly understood. Not quite as friendly or gregarious as its ocean-going cousins, the river dolphin is usually found in groups of only two or three - and often alone.
Pink river dolphins used to be native to almost every large river on the planet. Sadly, the river dolphins of Asia and India are extinct. And the river dolphins of the Orinoco and Amazon rivers are heading that way.
Although they are a protected species, the local fishermen still consider them to be rivals. River dolphins are caught and killed out of hand, and their flesh used as bait.
The best place to spot a pink river dolphin is at a lodge on the Yarapa River which is kept by the International Society for the Preservation of Tropical Rainforest.
