From the Telegraph UK:
"The dolphin appears to be healthy and normal other than its coloration, which is quite beautiful and stunningly pink.
"The mammal is entirely pink from tip to tail and has reddish eyes indicating it's albinism. The skin appears smooth, glossy pink and without flaws.
"I have personally spotted the pink dolphin 40 to 50 times in the time since the original sighting as it has apparently taken up residence with its family in the Calcasieu ship channel. ..."
In my uninformed opinion an albino dolphin is not a strong survival trait since albinism is known to cause vision issues and/or blindness. I think they should catch it and put it in a marine park so the trait does not continue.
Humans have had an debilitating effect on animal natural selection. Example: Poachers slaughtering male elephants in Africa for their Ivory tusks have inadvertently created a slew of male, hybrid, elephants that have no tusks whatsoever. In other words, if you are male elephant and have no tusk, you are gonna to survive since there is no profit in shooting you. Hence, a weaker trait wins. (I am looking for a reference on this since I didn't realize this first.)
