Mary River Turtle Elusor Macrurus Cann and Legler, 1994

This turtle is characterised by a reversed sexual dimorphism, with the adult male weighing 5500 g, with a carapace measuring 420 mm, being significantly larger than the female that weighs 3500 g and measures 340 mm. This turtle possesses a distinctive massive tail that is more than half the length of the carapace in adult males. In all sexes and ages, the tail has a large precloacal portion and is laterally compressed. The head is relatively small for its carapace size, displaying a prominent headshield that becomes more distinct from the surrounding skin colouring with age.
