Museum scientists recently described the Gulf Coast Indigo Snake as a separate species from the similar Atlantic Coast snakes. These snakes are in decline due to habitat loss across the state, making it critical to understand the differences in populations for conservation efforts.

Indigos are really cool snakes and they’re the largest in North America north of Mexico. They were listed by the U.S. Fish and Wildlife Service during the 1970s as threatened species. The recent genetic study found two species of indigos in eastern North America and, therefore, it cut each of the known geographic distributions by half.
