The Pink River Dolphin

There are many species of dolphins in the world. The most unique, by far, is the pink river dolphin. These dolphins begin life as a gray color and slowly turn pink as they age. They can be anywhere from predominantly gray with a few pink spots, to nearly as pink as a flamingo. When the dolphins get excited, they can flush bright pink, like a human blushing.

Critter Man

With over 40 years of critter experience to my credit and hundreds of zoology teaching hours to people around the world, I have amassed not only a continuing thirst for critter knowledge but a desire to teach others all I can about the majesty and wonder of our natural world. Critter Science is a culmination of such knowledge.I have hands on as well as book acquired intel on all kinds of critters. Whether they're on land, sea, or air.I will never say that I know everything about all animals. That's impossible, even for a savant. But, that being said, ask me any animal question and I'll answer it. If I don't know the answer, I'll get an answer for you!Let it be said that I have been oft times accused of loving animals more than I love people. I can neither confirm nor deny this.
