The Thylacine, or Tasmanian Tiger, was declared official extinct in the late 1930s, but today people all over Australia claim to have seen one of these creatures. We sent our investigates to check out some of the most compelling sightings. You decide – extinct or not.

In this intriguing tale, our Animal X Natural Mystery Unit puts its investigative skills to the ultimate test in trying to track down a live Thylacine, a creature described as a ferocious killer. Experts believe the last of its kind died in an Australian zoo in the 1930′s. Dan and Nat head into the wild bushland of Western Australia to talk to a farmer who swears he has seen the creature dozens of times stalking prey on his property. Our camera traps may just capture proof that the Thylacine lives.

In search of the Thylacine, the Animal X Natural Mystery Unit heads to Australia’s fascinating and dangerous Tasmanian wilderness, where eye witnesses claim the creature still lives. They meet a local wildlife carer who is convinced Thylacines are alive but fears Tasmania’s pro-logging policy will eventually kill off any chance the species has for survival, as its habitat disappears. And we talk to Hans Naarding, a respected wildlife officer who flies from his home in Queensland, to Tasmania to the scene of his Thylacine sighting in an eyewitness account regarded as one of the most creditable ever.

Animal X also talks to Bob Paddle in an exclusive interview. Melbourne-based Paddle is the author of the Last Tasmanian Thylacine. He is also the president of the Australian Fauna Research Association. Animal X talk to experts about their theories, eye witnesses tell of their hair-raising experiences and conspiracy theorists explain why it is in the government’s best interest to keep the existence of the Thylacine hidden. Dan and Nat head to a restricted military area, where AX has gained exclusive rights to set up camera traps in a bid to gain evidence of the Thylacine’s survival. Is this creature still out there, stalking its prey?
