Where filamentous green algae were rare, total food bolus volume was reduced and E. macquarii only partially replaced it with other food items, including other vegetation, wood, and animal prey. This turtle is an adept bottom feeder, preying on terrestrial and aquatic insects, macroinvertebrates, crustaceans, algae, aquatic snails, worms, freshwater sponges and aquatic plants such as ribbon weed (Vallisneria sp.).

In combination, these responses resulted in a slower rate of digestion at 20 degrees C than at 30 degrees C. 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). Reproduction is oviparous and dioecious. Generalist consumers forage on a diversity of resources and have greater potential to ‘switch’ their diet in response to fluctuations in prey availability, in comparison to specialist consumers.
