南非的逆戟鲸大致可分成三类，A型逆戟鲸雄鲸及雌鲸最大可长达8.81米及7.9米，食谱包括鱼类，头足类，海鸟，鲸类，鳍足类，什至大白鲨也曾被A型逆戟鲸捕食。

第二类逆戟鲸是一类侏儒型逆戟鲸，雄鲸比A型逆戟鲸雄鲸短1.5米，雌鲸较A型的短2米，偏好进食中小型鲨类，牙齿严重磨损。

至于第三类主要是分布于爱德华王子群岛（Prince Edward Islands），形态及基因近似南极的浮冰型逆戟鲸，食性包括企鹅及鳍足类。

South Africa also boasts a population of killer whales around its Prince Edward Islands in the sub-Antarctic. This population bears some morphological resemblance to Antarctic Type B killer whales, to which they are also genetically closely related. However, at this point, it appears unlikely that this population is ever seen off mainland South Africa as the most northerly satellite-tracked individual, although coming close, did not overlap with killer whale sightings off the South African coast. Furthermore, no photo-identification matches have ever been made between killer whales from the Prince Edward Islands and South Africa.

Individuals at the subantarctic Prince Edward Islands (some of which are similar to type A; others appear similar to pack ice killer whales) prey on elephant seals, subantarctic fur seals (Arctocephalus tropicalis) and penguins.
