The Krefft's Short-necked Turtle (Emydura krefftii) is easily recognized by its bright to pale yellow facial stripe which extends back from the eye to the ear.
The shell is deep and oblong-shaped, with an olive-brown to blackish-brown carapace and blueish-green tinged plastron underneath (a distinctive feature of this species).
This species occurs only in Queensland.
