Habitat and EcologyHabitat and Ecology
Dusky dolphins take a wide variety of prey, including southern anchovy near the surface in shallower waters, as well as midwater and benthic prey, such as squid, hake, and lanternfishes. They may also engage in nocturnal feeding, in association with the deep scattering layer. New Zealand dolphins appear to engage in feeding deeper in the water column than do those from Argentine waters (Cipriano 1992; Wrsig et al. 1997).
