This dolphin may appear dark at a distance, but it has a complex pattern of white, gray, and black. The shape of its dorsal fin makes it easy to distinguish from other marine mammals. Unlike most dolphins, males are generally smaller than the females. Hector's dolphins rarely bow-ride, however, they wake-ride and follow alongside slow ships. These dolphins prefer to associate with slow or stationary ships over fast ones (over 10 knots) and may even avoid faster ships.
