The perentie is a known species of monitor lizard, which is the biggest in Australia and the third biggest in the world. They inhabit western and central Australia. The largest confirmed perentie specimen was 8.2 ft long. Occasional reports of perenties, or a species of perentie much larger, have been reported, reaching 18 ft. These giant perenties, or as the Aboriginals call it— the Debil Debil, coming from “devil”, with the word repeated to emphasize its large size. They’re described as being so large it can make it can make an ox fall down by a sweeping blow by their tail. Giant Perenties are described as moving in an awkward galloping motion. Most sightings are by Aboriginals due to the very remote location of them, with only a handful of outsiders seeing them. Although this cryptid is similar to the Burrunjor, also living in Australia, giant perenties are less bulky, have longer necks, have yellow and black skin and are smaller. One of the first recorded sightings was In 1931 when Explorer T.C Wollaston reported of an unknown perentie species that is yellow with black spots the size of a coin and averaged at 8 to 15 ft. In the same year, a prospector nicknamed Big Jim reported that while he was fossicking for opals, he came across an enormous 15 to 17 ft lizard resembling a perentie alarmingly close to him. He tried to ignore it until it made an unusual sound described as “a mix between a lion’s roar and a dog’s bark.” After this, Jim ran away in fear. Later in 1940, explorer Fred Blakeley started an expedition to find the giant perentie and came across footprints and an alleged skin of a 10 ft perentie killed at Weinikie Gold Field.
