	Limacina - Wikipedia, the free encyclopedia
		The sea butterflies from the family Limacinidae (Blainville, 1823) have evolved from fossils from the Middle Miocene.
		Shell sizes and thicknesses vary within Limacina, but they are still large enough to fit the snail.
		In arctic and temperate waters, the diameter of the shell does not superseed 15 mm.

	Limacina (Site not responding. Last check: 2007-09-29)
		The shelled pteropod Limacina is a rare visitor to surface waters of central California, but when present, can be incredibly abundant.
		Limacina are common in arctic and high latitude temperate waters, where they may have a shell diameter up to 15 mm.
		During daylight hours Limacina tend to migrate to deeper waters (down to 100 meters).

	Clione 14.02.
		The winged snail Clione limacina, a small mollusc floating in the water, is able to go without food for a whole year.
		Investigations at the Alfred Wegener Institute for Polar and Marine Research demonstrate that the snail’s ability to survive extended periods without nutrition is based on a combination of an extremely low metabolic rate, the breakdown of body cells and the utilisation of special lipids.
		The winged snail Clione limacina lives in oceans of temperate latitudes and in the Arctic.

		The thecosomatous pteropods in fiftysix plankton samples (28 horizontal surface and 28 vertical, generally 2000 m, hauls) were studied from the systematical and distributional points of view.
		Pteropoda do not exhibit conspicuous differences between veliger and adult shells, but there is quite an important difference between the protoconch and the rest of the shell, the former being very similar in several Gastropoda.
		The division of the genus Limacina into 3 subgenera, as proposed by Van der Spoel (1967), is also partially confirmed by the present study.

		Since they are capable of swimming through the water column with their foot, which has been modified into a pair of "wings," pteropods are also commonly referred to as "sea butterflies." The predatory naked pteropod, Clione limacina, lacks a shell and has a transparent body with reddish-coloured internal organs.
		It has a pair of tentacles that are used in overpowering its prey, particularly the shelled pteropod Limacina helicina.
		This latter species is a small, herbivorous pteropod that has a fl-coloured body and an external, coiled shell.

	American Society of Limnology and Oceanography
		Transfer of mycosporine-like amino acids (MAAs) from a natural phytoplankton assemblage to the herbivorous pteropod, Limacina helicina and from L. helicina to the predatory pteropod, Clione antarctica, was investigated in a coastal Antarctic system to evaluate the bioaccumulation and dietary alteration of MAAs.
		Dietarily derived MAAs were bioaccumulated in the pteropods with a concentration factor 2.2 and 2.4 for the first and second trophic transfers, respectively.
		A theoretical reaction scheme will be presented for the production of mycosporine-glycine, palythenic acid and palythine from phytoplankton derived shinorine and porphyra-334 via microbial and chemically mediated reactions.

		Adults of two species were found drifting along in the currents: an inch-long, roundish purple sea butterfly (Limacina helicina) and a larger orange sea angel (Clione limacina) which is illustrated here.
		Unlike their crawling relatives, these planktonic ocean nomads have an extremely thin outer shell, as in the case of Limacina, or no external shell at all, as in Clione.
		It uses adhesive, cone-like structures around the mouth to grasp the Limacina and then employs chitinous hooks and a rasping tongue, called the radula, to pull the prey from its shell.

		These sea butterflies (As opposed to the sea hares , which are different again!) may or may not have a shell.
		Their shells are most often found in fine, deep-sea sediments, where they are not lost or crushed amongst coarser sand, gravel and rocks.
		Another ciliary feeder is the shell-bearing sea butterfly, the Limacina (See: Limacina helicina).

		The oceanic assemblage (generally in waters > 2000m) includes salps, whereas the coastal assemblages (shelf break and slope) includes several species of euphausiids, including Antarctic krill (Euphausia superba) and Thysanöessa macrura, and the herbivorous shelled pteropod, Limacina helicina.
		Over much of the shelf region both the oceanic and coastal assemblages occur in varying mixes year to year with no clear boundaries between zones.

		The pteropods and amphipods are the most abundant animals found in our samples.
