The Dusky dolphin is energetic and playful, best known for its highly acrobatic behaviours. Being a member of the Odontoceti family dolphins are carnivorous feeding on a variety of fish. More research is needed to understand Dusky dolphin movements but it is believed that they have no set migration patterns or routes. The females give birth in winter and will nurse there young in shallower waters away from known predators. They are commonly known at Gough with frequent sightings also seen accompanying ships. Dolphins communicate using echolocation (using sound not eyesight) to locate, judge or detect invisible objects helping them navigate in the dark, search for food and make sense of their surroundings.
