Dusky dolphin

Introduction: Dusky dolphin are associated with the colder waters of the Benguela Current and are often seen in schools numbering several hundred. They are a favourite on dolphin cruises from Walvis Bay as they frequently ride the bow-wave of sea going vessels whilst indulging in spectacular aerial displays and high somersaults that any world champion gymnast would be proud of. Dusky dolphins communicate by a series of whistles, but it is not known if they have any sonar abilities when communicating to each other.
