With Cuvier's beaked whales found stranded more often than any other species of beaked whale, its global population is thought to be relatively large (1) (5). Coupled with its widespread distribution, this species is not believed to be undergoing significant declines. Nonetheless, there are a variety of threats that may be causing localised declines in its abundance (1). Although historically it has never been hunted in significant numbers, it is regularly reported as by-catch in other fisheries. Furthermore, overfishing may be reducing the amount of 'prey' available to species such as Cuvier's beaked whale. Probably the greatest current concern is the effect of acoustic pollution, associated with sonar and seismic exploration, on this species (1) (5) (7). In recent years, mass strandings of Cuvier's beaked whale have been found to correlate closely with military activities (1).
