Head is usually yellow with a darkened area on the dorsal surface. Limbs and tail yellow. Behavior Habits of the Radiated Tortoise are essentially the same as those of other land tortoises. They are diurnal, like warmth, drink a lot whenever they get the opportunity, though when forced to abstain they hold out well. During the hot season when the vegetation is parched and dry, they dig hole in the ground and take refuge in it as a way of avoiding dehydration and the excessive heat.
Eggs are almost spherical with brittle shells.
Hatchlings are brightly marked with flattened, rounded carapices. Diet Grasses, cactus and shrubs. Also mixed in are alfalfa pellets which have been soaked in water. The radiated tortoise is one of the rarest of the tortoises.
