The southern brown bandicoot (Isoodon obesulus) weighs just 1.4 kilograms, but over the course of a year this tiny digging marsupial can excavate more than 3.9 metric tons of soil as it builds its nests and [...]

Now we have word of a new threat to these unique, egg-laying mammals: inbreeding, which has put the platypuses living on two small Australian islands at enhanced risk of disease. According to research published March [...]

The thick, waterproof fur that once made the platypus (Ornithorhynchus anatinus) a valuable target for trappers may soon present another danger for the unique mammal: Australia could soon end up being too hot for the species to survive. Platypus fur is so warm and watertight that it insulates the semiaquatic animals from virtually all heat [...]
