Mississippi Gopher Frog: Rana sevosa formerly occurred in the Coastal Plain west of Mobile Bay from Alabama across Mississippi and into Louisiana's Florida Parishes; it is now known from a single site in Mississippi and is federally listed as Endangered.
Our perception of rarity hinges on the difficulty of determining the presence of a species. The chances of discovery are low for a frog that stays beneath the ground. Most frogs are located by listening for calling males at night at a breeding pond or catching the tadpoles with a dipnet. What if adult gopher frogs call on only one night each spring at a particular breeding site? If no one is there to hear them, their presence goes unnoticed.
Between the disease and a shrinking natural habitat, the frogs face extinction. EXTINCTION means forever!
