A marmoset tries to stay cool as he relaxes in the shade of a garbage can lid at Forte Duque de Caxias on a hot spring day in Rio de Janeiro on September 25, 2024. The small primates are native to South America and along with tamarins, are commonly found throughout the Atlantic Forest Environmental Protection Area.
