Recent graduates of marine biology (in titling) and recently consolidated as "Marine Mammals of Oaxaca, Biodiversity and Conservation, AC" we held the first continuous monitoring of marine mammals in the Oaxacan coast, promoting conservation and sharing our passion for Science, we sailed the seas in search of those extraordinary beings, inter alia making, photo-identification efforts of several cetacean species present in the area to know the status of their poblaciones.Parte of this effort is my project thesis focused on a relatively small species of dolphin known by the scientific community: the stenosis. I hope you enjoy the video as much as I do so. Raul Ramirez
