The outlook is even bleaker for amphibians, where upwards of 40% of species are in danger of extinction. The researchers, led by Neil Cox of IUCN-Conservation International and Bruce Young of NatureServe, highlight that efforts to conserve other threatened animal classes, such as mammals, birds and amphibians, will co-benefit many threatened reptiles.

And, efforts to conserve one reptile species, in many cases, will benefit others–underscoring the need for action. “Although some reptiles–including most species of crocodiles and turtles–require urgent, targeted action to prevent extinctions, efforts to protect other tetrapods, such as habitat preservation and control of trade and invasive species, will probably also benefit many reptiles,” state the authors of the study. The reptile class comprises turtles, crocodiles, snakes, lizards and the tuatara.

Here are three of the rarest snake species in North America, and where you might be fortunate enough to locate them. 1. Rim Rock Crown Snake Rarely photographed and strikingly elusive, the rim rock crown snake showcases its d.
