Two jellyfish species are documented for the first time from the Lebanese waters. A string jellyfish, siphonophore, Apolemia cf. uvaria, was observed first on 25 May 1993, at 5 m depth, off Tripoli (north of Lebanon) and recently on 25 April 2021 photographed off Saida (south Lebanon) at 16 m depth. The other species, a rare ctenophore, venus girdle, Cestum veneris, was observed and photographed at around 2 m depth off Tyre (south Lebanon), on 4 March 2021.

Keywords: Siphonophorae, Ctenophora, Apolemia cf. uvaria, Cestum veneris, Lebanese waters, eastern Mediterranean Sea
