Fauna of Australia species are nocturnal and many arboreal. Two of the five living species of monotreme occur in Australia: the platypus and the short-beaked echidna. The monotremes differ from other mammals in their methods of reproduction; in particular, they lay eggs instead of giving birth to live young. The platypus—a venomous, egg-laying, duck-billed amphibious mammal—is considered to be one of the strangest creatures in the animal kingdom. When it was first presented by Joseph Banks to English naturalists it was thought to be so strange that it was a cleverly created hoax. The short-beaked echidna is similarly strange, covered in hairy spikes
EDGE species cetacean) the bumblebee bat (arguably the world’s smallest mammal) and the egg-laying long-beaked echidnas are highly threatened yet remain poorly understood and are frequently overlooked by existing conservation frameworks. Recent research indicates that 70% of the world’s most threatened and evolutionarily distinct mammal species are currently receiving little or no conservation attention. The Zoological Society of London (ZSL) has launched a global conservation initiative, the EDGE of Existence Programme to raise awareness and funds for the conservation of these species. Some species are more distinct than others because they represent a larger amount of unique evolution. Species like the aardvark
