Ecology
The South African squid feeds on small fishes. It forms dense breeding aggregations in bays between Cape Point and Port Elizabeth in summer, laying sausage-shaped bunches of egg bundles on the sea floor. The young are transported west by the Agulhas Current and mature on the Agulhas Bank. They then migrate eastwards as adults back to their spawning grounds.The species is extensively exploited by commercial fisheries. Its natural predators include: Short-tail stingray
