Descrição
Killer whales (Orcinus orca) are known to prey on a wide variety of marine mammal species, including large and small cetaceans, as well as pinnipeds (Jefferson et al. 1991). No well-documented records of killer whales feeding on dusky dolphins (Lagenorhynchus obscurus) have been reported in the literature. Wursig and Wursig (1980) reported one second-hand account of pre-dation on dusky dolphins off Peninsula Valdes, Argentina. Accounts of killer whales preying on other species in the genus Lagenorhynchus are also infrequent (Dahlheim and Towel1 1994), especially given that these animals are both regularly observed in similar habitats. We present accounts of four killer whales preying on dusky dolphins over a period of 11 d off Kaikoura, New Zealand (42°25'S, 173°42'E).

Descrição dos passos do método:
- During four days, between 4 and 14 November 1995, four adult killer whales (two males and two females) were observed to chase, and on seven occasions kill, dusky dolphins (Table 1). The four killer whales involved were first photo identified in the Kaikoura area in 1988 using their saddle patches and nicks on their dorsal fins. They have been photo identified near Kaikoura on a number of occasions since then. The animals are referred to in this report by their catalog numbers: NZ 39 (female), NZ 40 (male), NZ 41 (male), and NZ 42 (female).
