Attempts have been made to gather baseline information on the bio-ecological and population aspects of cetaceans in the region. Opportunistic and systematic surveys have confirmed the presence of the Atlantic spotted (<i>Stenella frontalis</i>) and bottlenose (<i>Tursiops truncatus</i>) dolphins. Encounter rate with dolphin groups is about 70%. Preliminary results indicate that at least a proportion of the population is resident to the area, with recaptures ranging from a few days to at least 12 years.
