herpguy Posted January 31, 2006 Share Posted January 31, 2006 I found this picture of a pink dolphin. Amazing, I wonder why they're pink. Here is the article. Link to comment Share on other sites More sharing options...
AzurePhoenix Posted January 31, 2006 Share Posted January 31, 2006 I don't know the reason, other than that perhaps being the biggest predators in relatively murky waters, they don't need to block as much sunlight or blend in as effectively. Sheer speculation of course. I've seen them much pinker than that one (in river dolphins at least). They really are quite neat. Link to comment Share on other sites More sharing options...
AzurePhoenix Posted January 31, 2006 Share Posted January 31, 2006 your own article says this One theory is that the dolphins lost their need for camouflage because they live in brackish water where rivers meet the sea—areas where predators like sharks aren't found, Walker said. The pink color is believed to be caused by blushing, the flushing of blood to the skin to regulate body temperature. Link to comment Share on other sites More sharing options...
