Facts about this animal
The radiated tortoise has a oval, extremely elevated, smooth carapace. Each of the shields bears a distinct pattern of alternate radiating bands of yellow and dark brown. Usually the yellow lines are narrower than the brown, but sometimes the reverse is the case. In very large specimens, of over 400 mm carapace length the characteristic pattern might be missing; also some entirely yellowish specimens have been recorded. The radiant pattern is also visible on the marginals and on the plastron. The head is yellow with a black top. The tail is ending with a spur-like scale.
