It is one of the most beautiful tortoises in the world and also one of the most threatened: collection for the pet trade and for meat has decimated it within a few decades.

Fun facts

  • Its pattern of yellow lines radiating from the centre of each scute is unique and has been precisely the cause of its misfortune: it is one of the tortoises most sought after by the illegal pet trade.
  • In 2018 more than ten thousand live radiated tortoises were seized in a single house in Madagascar, one of the largest wildlife seizures in history.
  • It can live more than a hundred years: Tu'i Malila, a radiated tortoise supposedly given by Captain Cook to the royal family of Tonga, died in 1965 aged at least 188.
