Cephalorhynchus heavisidii is found in coastal waters off of Africa’s Southwestern coast, from central Angola to the southern-most tip of South Africa. This species usually remain within 8 to 10 km of the shoreline, but has been sighted up to 45 nautical miles from the coast. While some studies suggest that Cephalorhynchus heavisidii does not migrate significant distances, and that there are resident dolphins in some areas, this is not well established. One study tracked a juvenile male that swam 158 km north of where he was tagged. Another juvenile male traveled 137 km north of his tagging site over a 17 month period, suggesting that average daily movements might be small. This species appears to have low population densities of around 5 individuals per 160 km.
