A general lack of data about Arnoux's beaked whale means that its global population and conservation status are unclear. It is, however, generally thought to be rare and therefore may be adversely affected by some of the threats that are known to be causing declines in other beaked whale species. While this species is not generally targeted directly by commercial fisheries, it may be caught incidentally during drift-netting. In addition, commercial fishing in Antarctic waters may reduce food supplies for this species, particularly as a significant proportion of these fisheries are illegal and unregulated. Other issues may include climate change, as well as the use of active sonar by military vessels, which has been implicated in mass strandings of some beaked whale species (1).
