Relatively little is known about the Annam leaf turtle’s behaviour and biology in the wild due to its extreme rarity (5); however, a few captive individuals have been studied. It is an omnivorous turtle that will readily eat fruit, fish and invertebrates (5) (6). A semi-aquatic creature (1), the Annam leaf turtle feeds both on land and in water (7). It forages during both the day and night, although is typically more active at night, tending to remain well hidden amongst vegetation during the day (7). Like all turtles, this species has no teeth, but instead uses its sharp bony jaws to slice through its food (8).
The Annam leaf turtle typically mates in water after dark, and the act itself can be rather aggressive (7). The female digs a hole in soil in which she deposits the eggs. The entire nesting process takes several hours as the female carefully packs down the soil with her shell after covering the eggs. After about 80 to 90 days, the eggs hatch, and the young emerge, resembling miniature adults in appearance (7).
