Dusky dolphins are some of the most acrobatic of all dolphins. They are well known for their extraordinarily high leaps and somersaults. Dusky dolphins are often seen with seabirds and frequently associate with other cetaceans. These dolphins are easily approached and seem to enjoy contact with boats and humans. The three main types of breaching performed by dusky dolphins are arc shaped leaps, lobtailing, and high somersaults and twists.
The Dusky dolphin is extremely similar to the Pacific white-sided dolphin. Some experts have even suggested that they belong to the same species.
