The Platypus is a semi-aquatic mammal that is found in freshwater environments within the eastern states of Australia, including Tasmania, as well as on Kangaroo Island. Its thick brown fur serves as insulation, and its distinctive, skin-covered duck-like bill helps it to detect the electrical fields of its prey. The male Platypus is the only venomous mammal in the world; it possesses a venomous spur on the inside of its hind leg.
Threats to this iconic monotreme include habitat pollution and degradation as well as predation by feral animals. As well as being listed as near threatened on the IUCN Red List, the Platypus is listed as endangered in South Australia and Victoria and there are fears that recent droughts, fires and floods in Queensland and New South Wales have negatively impacted local populations.

The Eastern Quoll is a medium-sized carnivorous marsupial that was once common throughout south-eastern parts of the country, but which suffered from predation by feral cats and the introduced Red Fox. Today, this endangered species occurs naturally in the wild only in Tasmania, though conservation efforts operate on the southern mainland. It prefers dry grasslands and forests where pasture grubs are plentiful.
A nocturnal and solitary animal, and an impressive hunter, the Eastern Quoll sleeps during the day in its nest in an underground burrow under the rocks, or under fallen logs, and then at night scavenges for carrion on the forest floor.
An adult male is about the size of a small domestic cat, averaging 60 centimetres in length; a female is slightly smaller. The Eastern Quoll is distinguished from the larger Spotted-tailed Quoll by the absence of spots on its tail and the presence of only four toes on each hindfoot.
