NEW COLORFUL SNAKE SPORTS HORNS As you can see from the vivid pics, this snake's body is colored a striking black and yellow. The new species measures 2.1 feet in length and has horn-like scales above its eyes. No one seems to really know why snakes like this have horns, although there's been a lot of speculation. The horns could help to protect the eyes, or they might be used in visual displays, with maybe the best-horned snake getting his or her preferred mate. Perhaps they serve a variety of functions.
