What are pink dolphins?

Pink Dolphin

Pink dolphin can refer to freshwater dolphins that are found in South America and China or to the rare pink bottlenose dolphin that was sighted in a lake in Louisiana, USA.

The first, and likely only, pink bottlenose dolphin was spotted swimming in Lake Calcasieu, an inland saltwater lake in Louisiana, USA, in 2007. "Pinky," as it is now called, is actually an extremely rare albino dolphin, of which there are only 14 known in the world, with "Pinky" being the only pink one. The others are white.

Pink river (freshwater) dolphins are found at the mouths of the Amazon and Orinoco Rivers in South America. They are called botos. Also, the Yangtze River in China has some, called baiji.

The pink dolphin is an albino dolphin, although it does not look white. The reason for this is because it has a very thin layer of fur. It has red eyes, which provide proof that it is albino.
