Hundreds of dead penguins and other sea animals in Brazil have washed up on Sao Paulo's shores and scientists are investigating the causes, environment officials told Folha Online news agency.
Sao Paulo University biologists and a wildlife research centre are looking into the possible reasons for the animal deaths, the institute said.
Praia Grande authorities have ruled out pollution, saying preliminary investigations point to starvation as the cause.
The most likely scenario for the penguin deaths is exhaustion and hunger during their long migration from the waters off Argentina's southern Patagonia region, said Andrea Maranho, a veterinarian for the Sea Animal Rehabilitation Centre in Praia Grande.
