Many people around the world have never heard of
the Amazon Pink River Dolphin, and those who tell tales of having spotted
one are often regarded with disbelief: “Err... what have you been drinking?” But Pink
River Dolphins are real!
From Wikipedia: The
pink dolphin lives in the freshwater of the Amazon River. This species
looks like the grey dolphin, but individuals are bigger, and instead of a
dorsal fin they have a hump on their back. Their tails are also bigger.
Because they are unfused, the neck vertebrae of the Amazon river dolphin
are able to turn 180 degrees.
The pink dolphin has
been listed as endangered by the International Union for Conservation of
the Nature due to pollution, over fishing, excessive boat trafficking and
The brain of the river
dolphin is 40% larger than a human brain.
