Sampling depth (Antarct., sub-Antarct.) : 0-1000 m.
Although the geographical distribution of this species seems cosmopolite, the list of studied authors shows that cold septentrional (northern) waters and Antarctic waters are preferable localities, even at a latitude of Taiwan (cf. Hsieh & al., 2004 (p.398, tab.1 & fig.2).
Observed in ballast waters of ships at San Francisco.
Remark concerning Oithona helgolandica: The rough description of Oithona helgolandica was done from a male found near Helgoland, the female was never described other than by synonymy with O. similis Claus,1866. The opinion put forward by Sars (1918, p.207) seems well founded. Under these conditions, the arguments developed by Crisafi (1959) are not retained, and this species is considered as doubtful or a synonym of O. nana as formulated by Rosendorn (1917) and Sars (1918). Nishida & al., 1977 (p.151) consider this form as doubtful. Also the authors after Claus (1863) who cite this form refer most often to Oithona similis.
