In addition to acoustic-behavioral research, the team documented, identified and photographed thousands of images in the area under investigation. Individuals in the population were identified by photo ID photographs of the pattern of pigmentation on the underside of the flukes and by the profile of their dorsal fin.
About 40 individuals were photo IDed, out of dozens of whales visiting the area each year. This part of the study contributes to the conservation of the local population. In the coming months, the researchers will work on the images, videos, and five hours acoustic recordings, in cooperation with parallel research groups around the world, to extract the desired product of social calls and their observed behavioral context.
In the long term, using the results of the research, research and engineering tools will be designed to improve whale recordings throughout the globe.
The study also documented three other marine mammal species:
Dugong dugon – an endangered herbivorous marine mammal , one of four living species of the order Sirenia
Spinner dolphin – Stenella longirostris
Indo-Pacific humpback dolphin – Sousa plumbea
