Amazon river dolphin (Boto)

Characterized by their light pink hue, "botos are the largest of the four river dolphin species, reaching up to eight feet long and 450 pounds. They have powerful flippers and tail flukes and a modified hump in place of a dorsal fin . . . Humans are the only threat to Amazon river dolphins, hunting them for catfish bait or trapping them accidentally in gill nets. Traditional Amazonian belief holds that the boto is a magical being able to take the form of a human and come ashore—with a hat to hide its telltale blowhole." Amazon river dolphin population numbers are predicted to fall by 95 percent in less than 50 years.
