Pinky the dolphin
In 2007, a Louisiana boat captain spotted a pink dolphin swimming with a small group of bottlenose dolphins in Lake Calcasieu, an inland saltwater estuary north of the Gulf of Mexico.
Nicknamed "Pinky," the dolphin is entirely pink in both skin and eyes but shouldn't be confused with the Amazon river dolphin, an entire species of white dolphins discovered in the Amazon river. (The Amazon river dolphin isn't a true albino.)
Just like any respectable celebrity, Pinky has his own Facebook fan page.
