A space for the Freshwater group to use to share information.

The largest of the river dolphins, this species is not to be confused with the [|Tucuxi] (//Sotalia fluviatilis//), whose range overlaps that of the Amazon River Dolphin but is not a true river dolphin. Because they are unfused, the neck vertebrae of the **Amazon River Dolphin** are able to turn 180 degrees. The pink dolphin lives in the freshwater of the Amazon River. This species looks like the grey dolphin, but individuals are bigger, and instead of a dorsal fin they have a hump on their back. Their tails are also bigger. The pink dolphin has been listed as endangered by the International Union for Conservation of the Nature due to pollution, over fishing, excessive boat trafficking and habitat loss. The brain of the river dolphin is 40% larger than a human brain.

I never new that piranhas live in the amazon river ( jaydene)
