Pinky, a pink dolphin that is sometimes spotted in Louisiana, recently made an appearance as it swam beside a boat full of people. But what gives Pinky its pink color? Wthout genetic testing, experts can’t know for sure. But they have some theories. Pinky was spotted first in 2007 with its mother, who had normal coloring. The pink color could mean that Pinky is albino. Or it could be a genetic variation that made the animal pink. Regardless, a pink dolphin is a rare sight and one that’s sure to cause a stir.
