The hourglass dolphin (Lagenorhynchus cruciger) is a small dolphin in the family Delphinidae that inhabits offshore Antarctic and sub-Antarctic waters.[3] It is commonly seen from ships crossing the Drake Passage but has a circumpolar distribution.
The species was identified as a new species by Jean René Constant Quoy and Joseph Paul Gaimard in 1824 from a drawing made in the South Pacific in 1820.[4] It is the only cetacean to have been widely accepted as a species solely on witness accounts.
