Camylla Pereira da Silva and Robson Teixeira Rollo demonstrate a snake tong at a wildlife clinic associated with the ongoing construction of the northern outer beltway of São Paulo, Brazil. The animals that come into the clinic have been rescue from the path of the Rodoanel Norte by teams who go out in front of the construction to remove/relocate animals and rare plants. Animals that do not need additional care are realeased at safe locations, including forest restoration locations, shortly after. Animals that do require medical attention are treated in this clinic, or, if required, in a better equipped clinic. Dead animals are frozen and made available to universities for research and eduction.
