Found in tropical coastal waters (Ref. 1522). Inhabits neritic waters over continental shelves (Ref. 80684). Usually found offshore. Commonly in large herds of 30 or more individuals (Ref. 801). Feeds on small schooling fish and squid; at night on creatures associated with the deep scattering layer (DSL), which migrates towards the surface in the dark (Ref. 1394). Preyed upon by great white sharks (Ref. 8891). Delphinus capensis tropicalis: They were reported to bow ride although not in areas particularly where hunting occurs. Schools in offshore areas are somewhat larger than coastal ones. Some form mixed schools with spinner dolphins (Stenella longirostris), and remains on the outskirts of the spinner school generally.
