No population estimates available but presumably abundant judging by frequency of sightings. Probably circumpolar in pelagic waters of the Subantarctic and Antarctic zones, south of the Subtropical Convergence. Most records fall between 45&#176 and 65°S (Rice 1998). Seen to the SE of NZ and from outside territorial waters S of Aust. Confirmed record (skull) from Heard I. and unconfirmed sightings from there. Sighted in the vicinity of Macquarie I. (Bannister et al. 1996; Kasamatsu et al. 1988).

Described by Quoy & Gaimard (1824) as Delphinus cruciger. A well-established species. Validity of the six species in the genus confirmed on morphological grounds by Miyazaki & Shikano (1997). No subspecies described (Bannister et al. 1996; Rice 1998).

Pelagic and oceanic. Cold waters of polar and subantarctic zones in waters of about 0-12&#176C. Most sightings occurring at temperatures of <7.0&#176C. Rarely seen near land. In Antarctic, usually seen away from pack ice. May be found in cool currents associated with West Wind Drift. No key localities known in Aust. or Antarctic waters, but apparent concentrations in Whaling Areas* VI and I, and apparently commonly sighted around Heard I. (Bannister et al. 1996).

[* Six Antarctic whaling ares were demarcated at the Washington Conference of 1946 (at which the beginnings of the International Whaling Commission were first laid down). These areas lie south of 40&#176S and extend to the Antarctic continent, or more practically, to the ice edge. Each comprises between 50&#176 and 70&#176 of longitude as follows:

  • Area I 120&#176W - 60&#176W
  • Area II 60&#176W - 0&#176
  • Area III 0&#176 - 70&#176E
  • Area IV 70&#176E - 130&#176E
  • Area V 130&#176E - 170&#176W
  • Area VI 170&#176W - 120&#176W]

No information

Very limited data (two specimens): fish and squid (Bannister et al. 1996).

Biological overview (based on non-Aust. information):

Maximum weight >94 kg; maximum length >1.74 m (male), >1.83 m (female) (Biermann & Slijper 1948; Brownell unpub.; Leatherwood & Reeves 1983). School size ranges from 1-100, with most being up to eight individuals. Acrobatic, rides bow waves. Has been seen in company with several other cetacean species including Long Finned Pilot Whales, Southern Bottlenose Whale, Arnoux's Beaked Whales, Killer Whales, Southern Right Whale Dolphins, Sei Whales and Fin Whales (Kasamatsu et al. 1988). Sounds include clicks and whistles. Few strandings are known.

[Bannister et al. 1996]

No information is available for any aspect of reproduction, including: length and weight at birth; age and length at weaning; age and length at sexual maturity; calving interval, season or calving areas. mating season or gestation period (Bannister et al. 1996).
