Biologists from Australia and the United States presented recent data on social interactions in a population of bottlenose dolphins (bottlenose dolphins genus Tursiops), wrote "Kompyulenta." The first article, which is to be published in the journal Biology Letters, is dedicated to male Tursiops. It has been established that male bottlenose dolphins are organized in groups of two or three individuals, who are guarding the female competitors from attacks — a so-called first-level union. Opponents, however, still persist in their attempts to "steal" the female, and in the battle pair or three males may
