An updated list released by the Australian government has confirmed the extinction of 13 endemic species. Among the species are 12 mammals and one reptile. The news now makes Australia the leading country globally in terms of mammal extinctions. Currently, more than 10% of the 320 land mammals that lived in Australia by 1788 are now extinct. The list is led by the recent extinctions of two species from Christmas Island, including the Christmas Island forest skink, the first reptile to go extinct since the European colonization of Australia.
