We studied a snake assemblage from an area of Caatinga with shrub and tree vegetation to describe the natural history of the snake species. A total of 636 individuals among 22 species from four families were recorded. The distribution of species abundances is log-normal; and the composition presents typical species from the Caatinga, with Oxybelis aeneus (Wagler, 1824) and Philodryas nattereri Steindachner, 1870 being the most common. The natural history of each species is described based on information regarding activity patterns, diet, habitat use, reproduction, and defensive repertoire obtained during the study, as well as on information available in the literature. The study area is located in a priority region for conservation and our results emphasize that conservation policies should be implemented in the region.
