In 2002 Correa’s Cartesian Dioramas was displayed at the Santander Cultural Center in the city of Porto Alegre. The series was inspired by animals found in the Amazon and concerns with the evolution of species and the scientific description of animals, though most of the animals consisted of a mixture of different species that seem likely to exist. The Diorama was then divided into individual species to be described in terms of their internal structure, habits, habitat and other features to fully describe their hybrid existence as plausible. Then he began work on the skeleton series where he revealed the inner surface of his species, their bone structure in full detail and richly explained. These works were in the 2003 exhibition Perverse Nature, held at the Estate Museum of Rio Grande do Sul – Ado Malagoli.
