Acteon antarcticus is a species of sea snail, a marine gastropod mollusc in the family Acteonidae. [1]
The shell of Acteon antarcticus is smooth, cylindrical, and oval in shape, with a maximum length of 6.6 mm. It is characterised by fine transverse lines and a long, smooth aperture that tapers slightly at the base. The central region of the shell exhibits distinct folds, while the outer lip is thin and sharp, lacking any thickened margins.
Acteon antarcticus is a marine gastropod species found in subantarctic waters, primarily in the Southern Ocean. Its known range includes regions surrounding the subantarctic islands and continental shelf areas near Antarctica. The species inhabits benthic zones at depths ranging from 120 to 340 meters, often occurring in cold, nutrient-rich waters with soft sediment substrates.
The brown skua, also known as the Antarctic skua, subantarctic skua, southern great skua, southern skua, or hākoakoa (Māori), is a large seabird that breeds in the subantarctic and Antarctic zones and moves further north when not breeding. Its taxonomy is highly complex and a matter of dispute, with some splitting it into two or three species: Falkland skua, Tristan skua, and subantarctic skua. To further confuse, it hybridizes with both the south polar and Chilean skuas, and the entire group has been considered to be a subspecies of the great skua, a species otherwise restricted to the Northern Hemisphere.
