Short-finned Pilot Whales are found in warm temperate to tropical waters of the world, generally in deep offshore areas (Reilly and Shane 1986, Olson and Reilly 2002). They do not usually range north of 50°N or south of 40°S. There is some distributional overlap with their long-finned relatives (G. melas is the only other species currently recognized), which appear to prefer cold temperate waters of the North Atlantic, Southern Hemisphere, and previously the western North Pacific. Only Short-finned Pilot Whales are currently thought to inhabit the North Pacific, although distribution and taxonomy of pilot whales in this area are still largely unresolved (Kasuya 1992). The two geographic forms of Short-Finned Pilot Whale off Japan have different, but partially-overlapping, distributions. The range includes the Sea of Japan. This species is not thought to inhabit the Mediterranean Sea, but it does occur in the southern Red Sea (Olson 2009). There are no confirmed accounts of Globicephala in the Persian Gulf, which is generally shallow with high salinity and turbidity (Boer et al. 2003, Preen 2004).
