Thanks to a work of awareness directed at the fishermen, whales are returning to reproduce on the southern coast of Brazil. This year 2012 has been viewed more than 100 (one hundred). They come every year from southern Argentina, this time of year. As they have a lot of trust in people, in the past they have been subject to indiscriminate fishing. Now they can be seen swimming near the surfers, and also boat trips are organized for people to see them.
