Riversleigh rainforest koala (SciiFii)

The Riversleigh rainforest koala (Nimiokoala australiensis) is a species of marsupial, closely related to the gray koala (Phascolarctos cinereus), that originally inhabited northwestern Queensland in the early-middle Miocene (23–16 million years ago) as an extinct species, Nimiokoala greystanesi, and was once extinct, but has since been brought back from extinction by SciiFii and introduced throughout the modern rainforests across Australia to help boost biodiversity. The Riversleigh rainforest koala is easily recognisable by its more prominent muzzle than that of gray koalas, resembling the possum snout, and the animal's much smaller size than other koalas, only growing to be about 25–30 centimeters (9.8-11.8 inches) and a weighing around 3.5 kg (7.7 lb) on average. The Riversleigh rainforest koala has a much more generalized, less specialized diet than other koalas, feeding on a wide range of leafy vegetation, not just eucalyptus leaves. Due to its small size, the Riversleigh rainforest koala requires a proportionately more intensive diet. It also has large eye sockets, which allows good night vision, and the Riversleigh rainforest koala is much more mobile than the gray koala. The structure of the ear of Riversleigh rainforest koala is similar to those of gray koalas; in conjunction with the large auditory bulliae, the Riversleigh rainforest koala is sensitive to and uses low-frequency sounds for communication, including to attract mates. The conservation status of the Riversleigh rainforest koala is Least Concern due to successful conservation efforts, the Riversleigh rainforest koala's wide range and its tolerance to many of the human activities.
