The caatinga is a unique type of dry forest found in northeastern Brazil. It is characterized by its thorny shrubs, cacti, and small trees, adapted to survive in a hot and arid climate. The region experiences a distinct wet and dry season, with most rainfall occurring between December and March. Home to diverse wildlife, the caatinga supports various species, including the endangered Brazilian three-banded armadillo and the caatinga horned frog. This ecosystem plays a crucial role in the local environment and culture, providing resources for the communities that inhabit the area.
