Southern Hemisphere in polar and cold temperate waters - Pelagic
Clione limacina was previously considered to have a bipolar distribution but Gilmer & Lalli (1990) show many internal and external differences between northern and southern hemisphere populations and consider the southern populations should be considered a distinct species, C. antarctica (Smith, 1902).
See message describing how an amphipod holds an animal of C. antarctica on its back to protect it from fish predation.
