The pancake tortoise is thought to be the fastest tortoise and the best climber, due to the lightness of its shell. Rather than ducking into its shell for protection, when threatened it will run for shelter in the rocks. The shell of the pancake tortoise is very flat, which makes it easier for the tortoise to right itself when overturned. They overturn frequently, due to their habit of climbing on and over rocks. These tortoises are surprisingly social, and get along well in a group as long as there is enough food for all. As many as ten tortoises have been found sharing the same crevice.
