Before a conservation plan for the false killer whale can be developed, it is imperative that more information about its population status and migratory movements be gathered. Until this happens, the impact of the threats faced by this species will remain unclear (1). Even with evidence to support the decline of this species, it may prove difficult to safeguard the false killer whale from military exercises and the use of sonar, as the development of protective legislation has become a contentious issue (8).
