A photo of a curious fish with one head but two bodies has been doing the email rounds. Is it real, or is it Photoshop? It's real, if the Texas Reptiles website can be trusted (and they sound like they know what they're talking about to me). The picture shows a siamese Northern Pike caught by Donald Tayer on the Ottertail River in North Dakota. The Texas Reptiles site also has an interesting gallery of other 'freaks of nature,' including a photo of an 18-foot alligator supposedly found on a construction site in Florida (the picture is real, but the gator was only 13.5 feet long).
