IS this Tasmania's biggest ever Tiger snake, trick photography or even a fake?The image has gone viral in Tasmania over the past month, and North-West snake catcher Michael Thow, who has been emailed the picture from 12 separate senders, believes it's ''a fair dinkum'' Tiger snake, potentially Tasmania's biggest if the photo was infact taken locally and was also genuine.''It's a fair dinkum snake, I believe it's a fair dinkum photo but the way they have taken the photo makes it look a lot bigger than it is,'' Mr Thow, from All About Reptiles, said.''It looks like a Tiger snake to me - I'd say that pretty confidently.''Mr Thow said he had been sent the image separately about a dozen times, adding the location of the photo, according to senders, was disputed, ranging from Lilydale, Scottsdale, Ouse and elsewhere in Tassie.The mystery was further complicated by contradicting claims the snake had been run over by a log truck, squashed by an excavator or killed by humans because of a perceived threat, he said.''It's (the email) been all over the place and the story changes every time,'' Mr Thow said.Mr Thow said he checked with Parks and Wildlife and was told, while they had seen the photo, no-one had officially reported the matter to the department.Mr Thow said if the photo was real and was taken in Tasmania and not on the mainland, then the snake could be of record length, being longer than the eight-foot Tiger recorded on Mt Chappell Island, next to Flinders Island, in the 1930s.He called on the man in the photo to come forward to help solve the reptile mystery.It was not illegal to kill a Tiger snake if a person perceived it a real threat to themselves or others, Mr Thow said.
