The bottlenose dolphin is one of the 34 best-known marine mammal species. It’s sociable, intelligent, and gained popularity in the ’60s thanks to the TV show, Flipper. This animal also has a unique feature: it can live in warm or temperate waters anywhere in the world. Additionally, the bottlenose dolphin boasts “special protection” status to avoid being hunted for commercial purposes. This is why when a pink subspecies appeared on the Calcasieu River in the United States, everyone was surprised and immediately wanted to see it.
