Studying animals that live in an environment radically different from ours is not an easy endeavor. Green Balkans’ experts, who have dedicated their time and effort to the study and conservation of cetaceans, spend days at sea in often severe and changeable conditions - in wind and cold, in heat and sun, with an indefinite length of working day. But as aquatic animals, dolphins do not spend much time on the surface, and this, among other obstacles, makes encounters with them extremely rare and unpredictable. As a result, the practice of satellite tracking of individuals has become established worldwide. The method allows to collect data on migrations of the species, their preferred habitat, seasonal distribution and even on some parameters of their behavior.
