Did you know? What is the difference between a tortoise and a turtle? They are both reptiles protected by a shell; however, a tortoise is land dweller while a turtle inhabits fresh or seawater. This blog post continues FCS’ series investigating the lives and interesting facts about sensitive species, and how humans interact with them. Our investigation in this post focuses on the rugged and elusive desert tortoise, a federally threatened species. The desert tortoise occurs in the Mojave and Sonoran deserts of the southwestern United States and Mexico. For 150 years it was understood that this tortoise was a single species with possible geographic variations. Like many things in the world of science, as knowledge and technology increase so does the ability to accurately classify species based on research and DNA evidence not just empirical data.
