The Endangered Aquatic Box Turtle

The Coahuilan aquatic box turtle is found in a unique valley in Mexico called Cuatrociénegas and no where else on the planet. It's the only aquatic box turtle in the world. Scientists estimate that only about 2000 exist in the wild and their habitat is quickly shrinking due to over use of water in agriculture, climate change and invasive species. University of Texas at Austin biologists have been studying them for about a decade.
