An updated list of Colombian siphonophore species was compiled from records in published and unpublished theses and final technical reports of Invemar projects. The most recent inventory published for South American marine waters contains some of the records, but leaves out others that are included in this document. There are records of 63 species of siphonophores in Colombian marine waters, 45 in the Caribbean Sea and 46 in the eastern Pacific Ocean, from the families Abylidae (9 species), Diphyidae (30 species), Hippopodiidae (5 species), Prayidae (4 species), Rhizophysidae (3 species), Physaliidae (1 species), Agalmatidae (9 species), Apolemiidae (1 species) and Physophoridae (1 species).
