The results of a first of its kind research study have revealed that dolphins have developed a number of similar personality traits* to humans, despite having evolved in vastly different environments! The study examined 134 male and female bottlenose dolphins from eight facilities across the world, with each dolphin’s personality being assessed by staff at the facilities. Among the shared personality traits between humans and dolphins: curiosity and sociability.
