A baby alligator was one of the wild animals photographed in Joao Castilho's "Zoo" series. All of the animals were photographed in homes. "I wanted to shuffle positions and boundaries that sometimes are too rigid," Castilho said.
A tortoise rests on a bed. All of the animals were cared for by nongovernmental organizations in Brazil.
"I think the photo of the puma (is) a special one because it's a really fascinating animal," Castilho said. "Paradoxically, it was one of the most dangerous I photographed. It is strange to be face to face with an animal that can potentially kill you."
Each photo was shot under natural light, and Castilho observed that the wild animals were "more silent and unpredictable" compared to domestic animals.
"Are not we also animals?" Castilho asks. "What brings us closer? What of them exists in us?"
A macaw takes a seat. For his shoots, Castilho tried to choose homes close to where the animals lived.
