numbat

The word numbat comes from the Noongar language of southwestern Western Australia, where noomba or numbat named the banded marsupial anteater now known to science as Myrmecobius fasciatus. The Noongar people of the Southwest Australian Floristic Region — one of the world's biodiversity hotspots, encompassing the jarrah and karri forests, the kwongan heathlands, and the coastal sandplains — had precise ecological knowledge of the numbat's relationship to termite mounds, its diurnal habits (unusual among marsupials; the numbat feeds in daylight), and its specific habitat requirements within the complex mosaic of southwestern Australian vegetation. The word was recorded by European naturalists in the nineteenth century and entered scientific literature, though it took considerably longer to achieve general use in popular natural history writing.

Myrmecobius fasciatus is one of the more extraordinary animals on the continent: the sole surviving member of the family Myrmecobiidae, with no close living relatives, it occupies a unique ecological position as the only Australian marsupial that eats exclusively social insects. Its tongue, which can extend to a length matching its head, is coated with sticky saliva and capable of insertion into termite galleries. An adult numbat requires approximately fifty thousand termites per day — a number that required intimate knowledge of termite mound distribution and productivity for Aboriginal communities sharing the landscape, who would have known which mounds were productive, which numbat territories existed, and where the animals could be found at what times of day. This ecological knowledge system, accumulated over tens of thousands of years, is partly what the word numbat carries.

By the time European settlement reached the southwest of Western Australia in the 1820s and 1830s, the numbat's range covered much of the southern part of the continent. By the mid-twentieth century, it had been reduced to two isolated populations in southwestern Western Australia, with the continent-wide range eliminated by foxes, feral cats, and habitat clearing. The numbat is now one of Australia's most critically endangered mammals, with estimates of the wild population ranging from under a thousand to perhaps fifteen hundred individuals. It is the faunal emblem of Western Australia — appearing on the state's Coat of Arms — a status that reflects both pride in the animal's uniqueness and guilt about its near-extinction under settler management.

Conservation programs for the numbat involve fox and cat baiting programs across its remaining habitat, captive breeding for insurance populations, and reintroduction attempts at sites with predator control. The word numbat appears on fundraising campaigns, school curricula, wildlife documentaries, and the emblem of the Western Australian state government. This degree of cultural visibility is new for the word: for most of its borrowed life in English, numbat was confined to specialist natural history writing. The extinction crisis has made it a word that carries weight beyond taxonomy — a word that is now a conservation argument in itself. The Noongar name for the banded anteater is now a word the world is learning to recognize as a measure of what has been lost and what might still be saved.
