(NEWSER) – Stephen Currie has a fairly delicate creature to thank in part for his survival, having been stranded for a month in the Australian bush amid 100-degree temps. Three weeks after police gave up the search for the man who went missing Dec. 29 in northern Queensland, Currie, 40, was found wandering a trail Tuesday—more than 30 pounds lighter and without shoes or a shirt—having lived off butterflies, fresh water mussels, and wild fruit, after getting lost on a walk, the Courier Mail reports. "By all money I thought he was gone," says a senior constable. "It's unbelievable. I phoned his mother straight away."
