Se identificó un total de 15 especies de sifonóforos calicóforos, todos ellos registrados por primera vez para esa región insular. La especie más abundante fue Chelophyes contorta (43%), con una densidad máxima de 135 ind./1000 m³, seguida de Bassia bassensis (23%). Las especies restantes fueron escasas y su abundancia relativa fue inferior al 10% Planktonic siphonophores sampled out near Easter Island during May 1992 were studied. Samples were taken with Bongo nets towed horizontally during 10 minutes between 5 and 10 meters of depth. A total of 15 species were identified, all of them are first records for the region. The most abundant species was Chelophyes contorta (43%), with a maximum density of 135 ind./1000 m³, followed by Bassia bassensis (23%).
