The Amazon river dolphin, also known as the pink river dolphin or boto, lives only in freshwater. It is found throughout much of the Amazon and Orinoco river basins in Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, and Venezuela. It is a relatively abundant freshwater cetacean with an estimated population in the tens of thousands. However, it is classified as vulnerable in certain areas due to dams that fragment and threaten certain populations, and from other threats such as contamination of rivers and lakes. The Amazon river dolphin is seen as a competitor for diminished fish stocks and is often killed or injured when people try to chase them away.

The constant stream of the water flowing around her body distracted her and she failed to notice another pair of eyes secretly watching her from the river bank. Suddenly, she shivered, overcome by the weird feeling that someone was watching her. A young man standing on the muddy bank smiled and stared brazenly at her naked body. She became embarrassed when she saw he was not averting his eyes but looking into her eyes as if they knew each other. Spontaneously, as if controlled by a sinister force, she stood up from the water exposing her naked body, and walked towards him. Her feet moved in small, constant steps, pulling her towards the man whose magnetism she could not resist and whose enchantment forced her to fall into hi...
