Horsup works in northern hairynosedwombat conservation, which at the time involved holding a piece of wombat excrement between his index finger and thumb.
The Northern hairynosedwombat is the largest of all the three species, weighing up to 40kg and measuring about 1m long (the females are slightly heavier than the males).
There are two other species of wombat, the common (or bare-nosed) wombat, which is not endangered and is found on the southeastern coast of Australia (in New South Wales, Victoria and Tasmania) and the southern hairynosedwombat, which is endangered and is found in arid, sandy pockets in the southern part of Australia (in South Australia and Western Australia).
