 Hector's Beaked Whale range

Hector's Beaked Whale, Mesoplodon hectori, is a small Mesoplodont living in the Southern Hemisphere. This whale is named after Sir James Hector, a founder of the colonial museum in Wellington, New Zealand. Some specimens washed up and sighted in California that were once thought to belong to this species have subsequently been shown to be Perrin's Beaked Whale. As of 2002, they have yet to be seen alive in the wild.
