This land turtle of the Testudinidae family is considered one of the most beautiful of all turtles (illustration). It is found in India and Sri Lanka, and the carapace length of the large females is about 25 cm, while that of the males is about 18 cm, making it small for a land turtle. The carapace is heavy and dome-shaped, with each carapace having beautiful yellowish-white radial patterns on a black background. The plastron also has similar patterns. The pattern on the carapace serves as a protective color in places with a lot of dead grass, but the patterns do not yet appear on newly hatched turtles. It is active in the early morning and evening, and feeds on vegetable matter such as grass and fruit. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
