Four young sea lions returned to the wild after being rescued by marine biologists and treated for various illnesses. The sea lions are survivors of various illnesses which they contracted off the coast of Peru caused by the elevated temperatures in the water because of the El Nino phenomenon, according to Carlos Yaipen, Director of Animal Science and Well-being Organization (ORCA).
