Pinky, the world's favorite and possibly only pink bottlenose dolphin, was seen again recently in her home waters of Lake Charles in Louisiana. Now Capt. Erik Rue, who first spotted Pinky in 2007, has important news about the dolphin.
"I've taken a ton of pictures of her mating and it proved she's a female," Rue told ABC News. It's official: Pinky is a lady.
While dolphins in the Amazon River are naturally and normally a pink hue, Pinky is unique because her coloring is the product of albinism. According to National Geographic, Pinky boasts two telltale signs of being albino: red eyes and blood vessels that show color through her pale, pigmentless skin.
But why is Pinky so pink when other albinos are typically pale or totally white? Naomi Rose of the Animal Welfare Institute told The Dodo, "the skin of dolphins is highly vascularized (lots of blood vessels and capillaries in the skin), and when they are active or hot, these blood vessels expand, and allow the dolphin to dump heat into the surrounding water." Rose added, "'Regular' bottlenose dolphins do this all the time too, but you can't tell because their normal skin pigment is gray."
Pinky isn't the only pink dolphin out there. This is Angel, an albino bottlenose dolphin that lives in the controversial Taiji Whale Museum. Many people have created a call to action to free this rare dolphin. For more information about the Free Angel campaign and to learn how you can help, click here.
Chinese White Dolphins also come in a rare pink, and nowadays it's getting even rarer. According to ABC News, "Their numbers have declined in Hong Kong's western waters to 62 today from 158 in 2003." To learn how you can help save these majestic creatures, click here.
Dolphins aren't the only unusually hued animals in the kingdom. While the common version of the katydid is green, there are rare pink katydids, and even more rare orange and yellow ones. All we need is a blue katydid, and then we'll have a whole pack of highlighters.
In 2003 Argentina's Mendoza City Zoo caused quite a stir when its polar bear, Pelusa, turned bright purple. The purple only lasted a few days and was caused by medicine being used to treat Pelusa's skin condition. Sadly, she has since passed away, but we'll always remember her as real life Photoshop.
In February 2012, Jersey Shore, Pennsylvania, residents Percy Emert and his wife Connie were shocked to catch this purple squirrel in their own yard. No one is sure how this squirrel wound up being purple, but leading theories are that the squirrel came in contact with a berry patch or that he fell into a port-o-potty. Then again, has anyone heard from Grimace recently?
Known as the Mwanza flat-headed rock agama, this lizard has earned popularity due to it having a similar color scheme to Spider-Man's famous costume. Only the males are this color, but don't worry; they won't be replaced by younger lizards in less than five years.
Gary over at GoldenMacaw.net raised these golden beauties from chicks. Their parents were normal blue/gold macaws, so these birds were a pleasant surprise. That's just what happens when you let Midas into the aviary.
No, your screen isn't stuck in sepia mode. This is the Qinling panda, a panda subspecies that's brown and tan instead of the typical black and white. There are only 200-300 Qinling pandas in the whole world.
