Arctic basins; Meso-Bathypelagic, concentrated between 900 and 1400 m, observation beween 650 and 2200 m; Commonly observed by ROVs, but rare in plankton net colelction; Re-examination of material from older cruises shows it to be common throughout the Arctic

Atolla

provided by wikipedia EN

Atolla is a genus of crown jellyfish in the order Coronatae. The genus Atolla was originally proposed by Haeckel in 1880 and elevated to the monotypic family level, as Atollidae by Henry Bigelow in 1913.^[1] The six known species inhabit the mesopelagic zone.^[2] The medusae possess multiple lobes called lappets at the bell margin.^[2] Medusae also have eight tentacles, alternating with eight rhopalia, and twice as many lappets occur as tentacles.^[2]
