The rarest dolphin the world? 🐬 This Risso’s dolphin has been affectionately named Casper due to his white complexion. He is one of just 3 white Risso’s dolphins in the world. He swims with his pod in Monterey Bay, off the coast of California, where lucky whale watchers sometimes catch a rare glimpse. #EarthCapture by adamernsterwildlife . . . . #Dolphins #RareAnimals
