A rare pink bottlenose dolphin was recently captured on video by charter boat captain Erik Rue. Pinky was first spotted by Rue in 2007. To everyone’s delight, Pinky made another appearance eight years later, and she might be pregnant!
According to scientist Greg Barsh, Pinky is most likely an albino. The pink hue comes from the blood vessels showing through her pale skin, which has no color. Albinism happens when there is a genetic mutation. The cells that make melanin, which produces the color in hair and skin, fail to make enough pigment, if any at all. People who have albinism have very pale skin, eyes, and hair.
Albinos can suffer from skin and vision issues as a result of their lack of melanin. Animals with albinism may be easily spotted by predators because they lack the appropriate camouflage. Therefore, albino animals, such as Pinky, are very rare in the wild.
