We found that the generalist Emydura macquarii consumes a varied diet (but mostly filamentous green algae) when primary producers are available and water is clear, but switches to a more carnivorous diet when the water is turbid and primary producers are scarce, following the predictions of optimal foraging theory. Care Level: Intermediate. Abstract. Emydura was a morphologically distinct form of Emydura macquarii, with the carapace (or upper shell) considerably more flared towards the rear than subspecies of Emydura macquarii from other rivers, a shell length of up to 25 cm and a golden-yellow iris with a yellowish inner ring.

(1998) studied the diet and digestive energetics of Emydura macquarii macquarii and found out the majority of the species' diet consisted of just two items, filamentous algae (53% by volume) and carrion (Teleostomi) (21% by volume). Subscribe to our Email Alert or feeds for the latest journal papers. The laboratory results suggest that fish carrion and aquatic and terrestrial invertebrates are probably essential dietary items of E. macquarii in the wild, because its metabolic requirements cannot be met from aquatic macrophytes alone.

Digestive efficiency of E. macquarii on a herbivorous diet at 30 degrees C (49%) was about half that of turtles on a carnivorous diet (91%), but they had longer transit times (118 h on the plant diet versus 70 h). Habitat: Rivers and streams with aquatic plants and plant along the river edges. Adults tend to eat a large proportion of vegetable matter such as fruits and water plants. Emydura macquarii produce 10–30 eggs per year in relatively shallow terrestrial nests, and they emerge en masse to deposit eggs during or after rain from October to December [ 24 ].
