The Bellinger River snapping turtle (Myuchelys georgesi) is a species of turtle in the Chelidae family endemic to Australia, in the Bellinger River and its tributaries, mid-eastern New South Wales, Australia.[2] Its preferred habitat is the deeper pools of the clear-water upstream reaches of the river, where the water flows continuously in most months over a bedrock basement and a boulder, pebble and gravel bed.[4] The species takes advantage of the highly oxygenated water with low particulate load by supplementing its oxygen uptake through cloacal breathing.[5] Myuchelys georgesi is essentially an omnivore, with tendencies leaning toward carnivory.[6] A high proportion of their food comes from benthic macro-invertebrate communities that are relatively sedentary and live in immediate association with the substratum, but with some terrestrial fruit and aquatic vegetation eaten. It nests from October to December, laying 10-15 oblong white hard-shelled eggs.[4] Within the Bellinger drainage, a very restricted range, the species is widely distributed and locally abundant. Current threats to its persistence include habitat modification and loss of native riparian vegetation, associated turbidification and sedimentation, predation by the introduced European fox, and competition with the recently introduced Emydura macquarii.[7]
