Sexual segregation in Indo-Pacific bottlenose dolphins is driven by female avoidance of males

In many species, males and females segregate from each other because they allocate time differently, forage on different foods, or tolerate predators differently. In Indo-Pacific bottlenose dolphins, male aggression can deter mixed-sex groups. When males and females encounter each other, males often join females while females often leave males. Females likely evade males to avoid aggression.
