Most have elongate bodies. Recently, some sources have recombined them with the Thecosomata under the Pteropoda (known as "sea butterflies"). Little is known about the Hawaiian fauna. In addition to Cliopsis krohni, four other species have been recorded from the north Pacific near Hawaii. Thliptodon diaphanus (Meisenheimer, 1903) in the family Clionidae was photographed off Kona, Big Island by Boz Johnson during a black water dive. The photo, posted to the Blackwater Photo Group on Dec. 28, 2021, can be seen here. Three other species have been collected in the general vicinity of Hawaii based on the range maps in Pelagic Molluscs on the Marine Species Identification Portal: Hydromyles globulosa (Rang, 1825) in the family Hydromylidae Notobranchaea inopinata Pelseneer, 1887 in the family Notobranchaeidae Pneumodermopsis ciliata (Gegenbaur, 1855) in the family Pneumodermatidae Cliopsidae
