The land mullet (Bellatorias major) is one of the largest members of the skink family (Scincidae).
The species may reach total lengths of up to 60 cm (23.6 inches). They are uniform glossy black to brown, with a paler ring around the eye. Their colour, along with their large size, allow them to maintain a body temperature of 30 degrees Celsius; they spend much of the day basking in the sun. Adult males have slightly shorter bodies but slightly longer forelimbs and heads than adult females. The ventral side (belly) ranges in colouration from auburn (orange-brown) to white, Juveniles have prominent cream lateral spots.
It is long-lived - with one captive female lizard known to have lived for at least 23 years.
The common name “land mullet” is said to date back to Longman (1918), who reported it to be in common usage for the species around Tamborine Mountain. The name probably alludes to the superficial resemblance to the homonymous fish, which has a similarly blunt head, large scales and is of similar size and coloration.
