Peale Dolphins are the most common species in this area of Chilean Patagonia. However, little is known of their biology and behavior.
Incorporating the experience of CMMR Leviathan in the scientific study of marine mammals, we have initiated a systematic long-term study of populations of Peale dolphins that are frequently around the reserve.
Having identified the sites with the greatest presence of this cetaceans, the next step was the identification of individual specimens based on natural markings such as scars, pigmentation patterns and notches in the fins. This identification allows knowing whether they are always the same individuals who frequent the area (residents) or if they do through their migratory route, for future analyzing of the dynamic or time variation in these populations. Also, the determination of their population size, reproductive rate, sex and individual and group characteristic behavior.
Data collection is performed by non-invasive methods. The information is recorded through high-resolution photos, submarines and aircraft videos and forms of occurrence and behavior.
