This review presents an innovative approach to investigate the teuthofauna from the Southern Ocean by combining two complementary data sets, the literature on cephalopod taxonomy and biogeography, together with predator dietary investigations. Sixty squids were recorded south of the Subtropical Front, including one circumpolar Antarctic (Psychroteuthis glacialis Thiele, 1920), 13 circumpolar Southern Ocean, 20 circumpolar subantarctic, eight regional subantarctic, and 12 occasional subantarctic species. A critical evaluation removed five species from the list, and one species has an unknown taxonomic status. The 42 Southern Ocean squids belong to three large taxonomic units, bathyteuthoids (n = 1 species), myopsids (n = 1), and oegopsids (n = 40). A high level of endemism (21 species, 50%, all oegopsids) characterizes the Southern Ocean teuthofauna. Seventeen families of oegopsids are represented, with three dominating families, onychoteuthids (seven species, five endemics), ommastrephids (six species, three endemics), and cranchiids (five species, three endemics). Recent improvements in beak identification and taxonomy allowed making new correspondence between beak and species names, such as Galiteuthis suhmi (Hoyle 1886), Liguriella podophtalma Issel, 1908, and the recently described Taonius notalia Evans, in prep. Gonatus phoebetriae beaks were synonymized with those of Gonatopsis octopedatus Sasaki, 1920, thus increasing significantly the number of records and detailing the circumpolar distribution of this rarely caught Southern Ocean squid. The review extends considerably the number of species, including endemics, recorded from the Southern Ocean, but it also highlights that the corresponding species to two well-described beaks (Moroteuthopsis sp. B and Psychroteuthis sp. B) are still unknown.

这项审查提出了一种创新的方法，通过结合两个互补的数据集（头足类分类学和生物地理学的文献）以及掠食者的饮食调查，研究了来自南大洋的teuthofauna。在亚热带锋线以南记录了60个鱿鱼，包括一种南极绕极（Psychroteuthis glacialis Thiele，1920年），南极绕极13个，南极绕极的20个，南极区域性的8个以及偶极亚种的12个。一项严格的评估从列表中删除了5个物种，其中1个物种的分类状态未知。42种南大洋鱿鱼属于三个大的生物分类单位，即拟南芥（n  = 1种），近视类（n  = 1）和拟南芥（n = 40）。南部大洋洲teuthofauna的特征是地方特有的高水平（21种，占50％）。代表了十七种足纲动物，其中三个主要科是甲足纲动物（七个物种，五个特有种），om足纲动物（六个物种，三个特有种）和头足纲动物（五个物种，三个特有种）。喙识别和分类法的最新改进允许在喙和物种名称之间建立新的对应关系，例如Galiteuthis suhmi（Hoyle，1886年），Liguriella podophtalma Issel，1908年以及最近描述的Taonius notalia Evans。Gonatus phoebetriae喙用那些异名Gonatopsis octopedatus1920年的佐佐木（Sasaki），因此大大增加了记录数量，并详细记录了这种罕见的南大洋鱿鱼的绕极分布。这项审查大大扩展了从南大洋记录的物种数量，包括特有物种，但同时也突显了尚不清楚的两个喙的相应物种（Moroteuthopsis sp。B和Psychroteuthis sp。B）。
