Arrau turtles can reach up to 90 kg (200 lb) in weight and the carapace length is up to 1.07 m (3.5 ft).
Most individuals are considerably smaller with the average adult female having a carapace length of 64–71 cm (2.1–2.3 ft) and the average adult male 40–50 cm (1.3–1.6 ft).
In addition to an overall smaller size, males can be recognized by their longer tail and straighter carapace than the females.
Arrau turtles are brown, gray or olive-green, but the exact color varies depending on the algae growing on the carapace.
