The biology and ecology of this huge pond turtle are poorly known. It is reported that in the wild the giant Asian pond turtle feeds largely on aquatic plants, but in captivity they have an omnivorous diet (4).
Information regarding breeding in the giant Asian pond turtle also comes from observations of individuals in captivity. Males have been seen biting at the head and neck of females, which is likely to be part of an aggressive courtship ritual that lasts up to several hours (4) (5). Following this, the male mounts the female and tightly grips the female’s shell during mating. About a month after mating, the female lays a clutch of four to six eggs, which hatch after 100 days of incubation at 27 to 28° Celsius (5). The young hatchlings have a soft area in the centre of the plastron (6)
