The Sulphur molly (Poecilia sulphuraria), locally known as molly del teapa, is a species of fish in the Poeciliidae family. It is endemic to Mexico, specifically to the Baños del Azufre near Teapa, Tabasco. The Baños del Azufre are sulfidic springs that contain high concentrations of toxic hydrogen sulfide (H2S). Poecilia sulphuraria has apparently evolved the ability to tolerate the toxic conditions. It is critically endangered for now.
