Dark body, pale beak tip and paired broad teeth in adult males near the middle of an arched lower jaw. Probably predominantly deep offshore waters; many records are strandings.
Wildlife education
This record supports wildlife education. Aquarium-care questions are not assigned to this profile.
Wild marine mammal outside home-aquarium scope.
Wildlife reference only; unsuitable for home aquariums. No captive operating protocol is validated by this profile.
Outstanding care evidence
- Institutional lifetime husbandry and veterinary protocol
Identification
Dark body, pale beak tip and paired broad teeth in adult males near the middle of an arched lower jaw.
Names and Classification
A wildlife species in the family Ziphiidae. The accepted scientific name follows the Society for Marine Mammalogy checklist.
Adult Size
Museum reference length about 4.9 m and mass 1–1.5 tonnes; these are sparse-record estimates, not sex-specific averages.
Distribution and Habitat
Temperate Southern Hemisphere waters, with records around New Zealand, southern Australia and subantarctic islands. Probably predominantly deep offshore waters; many records are strandings.
Feeding and Ecological Role
Detailed diet unresolved; deepwater fish and squid are inferred as likely prey. Strandings underpin much of the available knowledge; field identification is difficult.
Reproduction and Life History
Breeding biology is little known; summer–autumn calving has been suggested around New Zealand.
Conservation
Data Deficient (IUCN global; 2025-2 categories reported by IUCN Cetacean Specialist Group; checked 2026-10-17). Global category is distinct from national protection; Data Deficient is not a low-risk category.
Responsible Observation
Observe quietly at a distance, avoid pursuit and feeding, and follow local marine-mammal rules. Report strandings to authorized responders.
About the Photographs
No verified, freely reusable photograph of a living animal was found during this search. The target is at least three images. Dead specimens, drawings, uncertain identifications and photographs with incompatible or unverified reuse rights were excluded.
Aquarium Suitability
Wildlife education only. This marine mammal is outside home-aquarium stocking and care guidance. Wild range and diet are not a captive operating protocol; this profile does not infer tank dimensions, water settings, acquisition advice or an institutional welfare plan.
