Albino Dolphin :) Pink due to it's albinism & the blood vessels that lie just below it's layer of blubber. Sometimes they are even pure white instead of pink. Very rare a tend to stress more than most other dolphins.
A new study shows that bottlenose dolphins assign themselves and each other signature whistles that serve as names in interactions with other dolphins. This makes dolphins the only animal besides humans to be known to call each other by name!
