Range Description
Gray’s beaked whale is primarily a southern Hemisphere cool temperate species, which is apparently circum-Antarctic in occurrence (Mead 1989, MacLeod et al. 2006). Most records are from south of 30°S. There are many sighting records from Antarctic and sub-Antarctic waters, and in summer months they appear near the Antarctic Peninsula and along the shores of the continent (sometimes in the sea ice). Many of the stranding records are from New Zealand, southern Australia, South Africa, Argentina, Chile, and Peru. The area between the south island of New Zealand and the Chatham Islands has been suggested to be a “hot spot” for sightings of this species (Dalebout et al. 2004). There is one record of a Gray’s beaked whale straying into the Northern Hemisphere, a stranding record in the Netherlands (Boschma 1950). This was almost certainly an extralimital occurrence.
