The three-toed snake-tooth skink (Coeranoscincus reticulatus) is a species of skink in the family Scincidae. It is endemic to south-eastern Queensland and north-eastern New South Wales, Australia. It occurs in subtropical rainforest, wet sclerophyll forest, and montane forest on rich dark soils on the coast and adjacent ranges; some coastal/island populations (Fraser Island and Cooloola) occur on pale sands in lowlands. Coeranoscincus reticulatus measure 67-195 mm in snout–vent length. The limbs are reduced with three digits in each. In 2016, the three-toed snake-tooth skink was added to the Australian federal government’s list of threatened species.
