The diets of 15 species of squaloid sharks caught between Walvis Bay and Cape Agulhas over a depth range of 50–1 016 m are analysed. The most common prey items were fish and cephalopods. Hake Merluccius spp. were common in the diets of Centrophorus squamosus, Squalus acanthias, and S. cf. mitsukurii. Myctophids were extensively preyed on by Centroscyllium fabricii, Deania calcea, D. profundorum, Etmopterus cf. brachyurus, E. compagnoi, S. acanthias and S. megalops, among others. The most common cephalopods in shark stomachs were Histioteuthis miranda, Lycoteuthis ?diadema, Octopus vulgaris and Todarodes angolensis. Crustaceans were uncommon prey of most species, except for Centroscyllium fabricii and Etmopterus cf. granulosus. Centroscymnus coelolepis was the only squaloid with cetacean remains in the stomach. That species appears to parasitize its cetacean victims.
