Indian Ocean humpback dolphin
Sousa plumbea ranges from Southern Africa to Western Indochina, including coastal areas along East Africa, the Middle East and India (Arabian Sea). This species does not exhibit large migratory behavior. This species has been reported to inhabit a variety of different coastal habitats, including both soft sediment (e.g. sand and sea grass) and hard sediment (e.g. rock and coral) marine habitats as well as estuarine habitats (e.g. lagoons, bays, rivers, and mangrove channels). Preference and prominence of any given habitat type is highly dependent on the geographical location of any given Indian Ocean humpbacked dolphin population.
