The East African black mud turtle is reportedly nocturnal. Individuals have been known to aestivate in underground burrows when the temperatures become too warm, too cold, or conditions become too dry, re-emerging again when conditions return to a suitable level (4). The diet includes insects, worms, snails, small fish, amphibians and crabs, as well as aquatic plants such as water grasses (2) (4).
In captivity, the East African black mud turtle has been recorded laying its eggs in February and March, with hatchlings emerging around 58 days later (when incubated at 28 to 30°C), although this may vary with location (4). Three to twelve eggs are produced per clutch by the female and buried in a flask-shaped nest cavity (2) (5). In the Seychelles, the Seychelles black mud turtle subspecies lays its eggs between December and February (1).
