Pink Dolphin
The Amazon River Dolphins in the waterways of South America are naturally pink. The dolphins are known to flush a dark pink when excited.
The colour of the dolphins depends upon the clarity of the water, with the sun’s rays causing dolphins to lose their pigmentation and become a paler pink. They’re also able to paddle forwards with one flipper whilst paddling backwards with the other flipper to help them manoeuvre when the river floods.
