Description Its shape is round, with a tan-colored patternless shell that is more flat than domed. The word “sulcate” comes from the Latin word sulcus, meaning a groove or furrow. In regard to the sulcate tortoise, this refers to the distinctive growth rings that are produced as the tortoise’s scutes grow with each seasonal cycle.
Diet They eat grass, flowers, weeds and cacti. Like all tortoises, they are herbivores.
Reproduction Breeding occurs anytime between June and the following March, though it is more common after the rains from September to November. Males become aggressive and can be seen plowing into one another to flip over the competition. After mating, the female will dig four to five nests before she decides which one will best suit her clutch.
