The aim of the project is to estimate population sizes, and to investigate the habitat-use and behaviour of the dolphins as well as potential human impacts on their environment. There are three dolphin species found in Namibian coastal waters, namely the Dusky, the Bottlenose and the Heaviside's Dolphin. Threats to dolphin populations include prey depletion, bycatch in fishing nets, pollution, uncontrolled eco-tourism and coastal developments that change the nature of their environment.
