* Australian Savannas: Aboriginal languages are spoken in the Australian savannas, with hundreds of distinct languages and dialects.
* South American Savannas: Languages spoken in the South American savannas include indigenous languages like Guarani, as well as Spanish, Portuguese, and other European languages.
