Saiphos equalis, the yellow-bellied three-toed skink, is a species of eastern Australian lizard. The lizard has attracted scientific attention due to its dual reproduction habits of producing young via eggs in coastal populations, or via live young in colder mountain regions.
Saiphos equalis grows to a length of 18 cm including the tail. It has a brown back and an orange belly. The skink is active at night, and feeds on insects.
