The Centre of Coastal and Marine Studies (Ceclimar) said on Friday veterinarians were investigating the deaths of the 512 marine animals which beached on the coast between the towns of Tramandai and Cidreira, some 100 kilometres from the state capital, Porto Alegre.

Some 30 samples from the penguins were being analysed at Porto Alegre University and results were to be released within a month, it added.

Ceclimar officials told Globo’s G1 website that veterinarians were puzzled by the large number of animals found and by the fact that they appeared well fed, not exhausted and without injuries or oil stains.
