Michael Sars

30 Aug 1805 - 22 Oct 1869, Norway

The Norwegian Michael Sars must be seen as the real founder of hydrozoan systematics, despite Linnaeus and some others had already named hydrozoans before him. He described the first hydrozoan life cycle (Corymorpha nutans)  and named many known species, e. g. :

Bougainvillia muscoides (Sars, 1846)
Rhizorhagium roseum Sars, 1874
Hydractinia carnea (M. Sars, 1846)
Hydractinia fucicola M. Sars, 1857
Leuckartiara abyssi (G.O. Sars, 1874)
Rathkea octopunctata (M. Sars, 1835)
Sarsia lovenii (M. Sars, 1846)
Sarsia tubulosa (M. Sars, 1835)
Corymorpha glacialis M. Sars, 1859
Corymorpha nutans M. Sars, 1835
Clytia gracilis (M. Sars, 1850)
Laomedea exigua M. Sars, 1857
Halecium pusillum (M. Sars, 1857)
Grammaria abietina (M. Sars, 1850)
Melicertum octocostatum (M. Sars, 1835)
Stegopoma plicatile (M. Sars, 1863)
