Bolson Tortoise (Gopherus flavomarginatus)
Also known as the Mexican giant tortoise or the Yellow-margined tortoise, the Bolson tortoise is a large species of gopher tortoise that is native to a region of the Chihuahuan Desert in north-central Mexico. Like other tortoises Bolson tortoises are herbivores and will feed on a variety of grasses, shrubs and herbs. They will dig small burrows and use them as refuge from predators and weather. These burrows are usually constructed in social aggregations and clusters can reveal the social structures of individuals.
Bolson tortoises are currently listed as vulnerable and their populations are in decline. This is due in part to over-collection for food and the pet trade and habitat destruction.
