Marinero de Agua Dulce

Marine science, biology of the seas, some dissident info and riot are here

The La Plata dolphin or Franciscana (Pontoporia blainvillei) is a river dolphin  that actually lives in the ocean and saltwater estuaries, rather than inhabiting exclusively freshwater systems. Found in coastal Atlantic waters of southeastern South America

Tonina (how is called in Brazil) have coastal habits and are therefore sensitive to driftnet fishing in shallow sites.
