Some of the freshwater rays that live in the São Paulo Aquarium arrived here after an apprehension by IBAMA that detected these animals being transported by mail. Since their arrival, the rays help us to raise public awareness about animal trafficking and the responsible acquisition of pets. Another origin of the rays that live here is through births.
