Additional Information | Obelia longissima may be confused with other Obelia species. For example, Obelia dichotoma may also be elongate but lacks the regular shape and extreme length of Obelia longissima (Cornelius, 1995b). Obelia bidentata has multiple branched stems even when young. Colonies of Obelia dichotoma may be distinguished from Obelia longissima growing in rockpools in spring by its long tubular, nearly straight and darkening internodes (Cornelius, 1995b). No reliable key is available to distinguish between the medusae of Obelia species (for discussion see Cornelius, 1995b). | ||
