Sea Angels
Sea angels (clade Gymnosomata) are a large group of small free-swimming sea slugs, not to be confused with Cnidarians (Jellyfish and other similar creatures), classified into six different families. They are pelagic opisthobranchs in the clade Gymnosomata within the larger mollusc clade Heterobranchia. Sea angels were previously referred to as a type of pteropod. Sea angels are also sometimes known as "cliones" but this is potentially misleading because the family Clionidae is just one of the families within this clade. Recent molecular data suggest the Gymnosomata form a sister group to the Thecosomata (other planktonic, weakly or nonmineralized gastropods), but this long-standing hypothesis has also had some recent detractors. Fossils of the group go back to the Middle Frasnian stage of the Late Devonian period. Distribution These organisms have a wide geographic range, from polar regions, under sea ice, to equatorial (tropic) seas. Description In this clade, the foot of t ...

Clione Limacina
''Clione limacina'', known as the naked sea butterfly, sea angel, and common clione, is a sea angel (pelagic sea slug) found from the surface to greater than depth.Gofas, S. (2012). ''Clione limacina''. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=139178 on 2012-07-23 It lives in the Arctic Ocean and cold regions of the North Atlantic Ocean. It was first described by Friderich Martens in 1676 and became the first gymnosomatous (without a shell) " pteropod" to be described.

Journal Of Experimental Biology
''Journal of Experimental Biology'' (formerly ''The British Journal of Experimental Biology)'' is a peer-reviewed scientific journal in the field of comparative physiology and integrative biology. It is published by The Company of Biologists. The journal is partnered with Publons and has two-way integration with bioRxiv. ''Journal of Experimental Biology'' is now a hybrid journal and publishes 24 issues a year. Content over six months old is free to read. History ''The'' ''British Journal of Experimental Biology'' was established in Edinburgh in 1923 (''Br. J. Exp. Biol.'': ). It was published by Oliver and Boyd and edited by F. A. E. Crew with an Editorial Board of nine members, including Julian Huxley. When the journal ran into financial trouble, George Parker Bidder II, the founder of The Company of Biologists, rescued it in 1925. Sir James Gray was appointed as the journal's first Editor-in-Chief in 1925 and the journal was renamed ''The Journal of Experimental Biology' ...

Pneumoderma Violaceum
The Pneumodermatidae are a family of sea angels, or small floating predatory sea snails or sea slugs. They are pelagic marine heterobranch opisthobranch gastropod mollusks in the clade Gymnosomata. These small pelagic snails lack shells (except in their early embryonic stage). They are carnivores, equipped with swimming parapoda (fleshy, wing-like outgrowths), strong jaws, and grasping tentacles, often with suckers resembling those of cephalopods. Genera Genera within the family Pneumodermatidae include: Genus: '' Pneumoderma'' de Roissy, 1805 * ''Pneumoderma atlanticum'' Oken, 1815 * ''Pneumoderma degraaffi'' van der Spoel & Pafort-van Iersel, 1982 – distribution: Sargasso Sea, length: 11.8 mm * ''Pneumoderma mediterraneum'' van Beneden, 1838 – distribution: Florida, Brazil, Mediterranean, length: 20 mm * ''Pneumoderma peronii'' Lamarck, 1819 – distribution: Red Sea * '' Pneumoderma violaceum'' d'Orbigny, 1836 – distribution: Bermuda, oceanic, length: ...
