This work shows the importance of the Caatinga Biome and its biodiversity of flora and fauna, as well as the existing Conservation Units. As it is an exclusively Brazilian biome with a significant number of endemic species, people need to know about it so that they can preserve and conserve it. Research was carried out and some of the most frequent species were surveyed. The data was organized in a software program that will be used by teachers as a teaching tool. The software contains relevant information so that teachers can work with their students in an interactive way.
