Penguins are considered sentinels of the oceans, thus contracaecuk of these birds provide knowledge of the source and intensity of human impacts over marine habitats in the southern hemisphere Boersma Spheniscidae on the coast of Rio de Janeiro State.
In this route, some specimens may deviate from the group, reaching more distant areas of the Brazilian coast, like Rio de Janeiro State and others beaches, where they are rescued.
