A major focus of the study is to determine the population size and family groupings of these whales. This is done by photographing individuals as they breach or break the surface. Examination of the characteristic scars and coloring on their tail flukes allows for the identification of individuals. So far, 258 whales have been identified, as well as 23 newborn calves. Another research goal is to understand the genetic relationships of the humpback population. By retrieving skin samples, they can be examined for genetic similarity, both within the waters of Madagascar, across the Indian Ocean, and throughout the Southern Hemisphere. A better understanding of how humpbacks migrate and mix with other populations will help in the design of conservation measures to protect them.
