Những sự thật hấp dẫn

• While native to Madagascar, radiated tortoises have been introduced to Réunion island and Mauritius.  The oldest known radiated tortoise was “Tu’i Malila”, who was reportedly a gift from Captain James Cook to the Tongan royal family in 1777.  While on a royal visit in 1953, Queen Elizabeth was introduced to Tu’i Malila.  Tu’i Malila passed away in 1966 at the estimated age of 188 and her preserved body is still on view in the Tongan National Museum.

Đặc điểm vật lý

The average radiated tortoise is approximately 35 pounds and 16 inches in length at adulthood. Extremities are yellow and the carapace, or shell, is black with a yellow star-like pattern radiating from each scute.  Their beautiful shells make them a prime target for the illegal pet trade.
