	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.

		When the prey is in the right position, with its shell opening facing the radula of Clione limacina, it then grasps the prey with its chitinous hooks, everted from hook sacs.

		The settled part of the collection, mostly the pteropod Limacina retroversa were released into 30-gallon containers previously filled with seawater using the diaphragm pump system.
		And, the pteropod, Limacina spp., was not as numerous as in previous broadscale cruises this year.
		Limacina retroversa were present at a few stations, but never reached the dominance they exhibited during the January cruise.

		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.

		Data from an 8 h transect across the Great South Channel (GSC) were analyzed on a continuum of spatial scales from coarse-scale (100 km) to micro-scale (mm).
		Abundance was determined for 12 taxonomic groups including: invertebrate larvae (ophiopluteus larvae, anthozoa larvae: Cerianthus sp.), hydroids, copepods (Calanus sp., Pseudocalanus sp.), pteropods (Limacina retroversa, Clione sp.), ctenophores (Mnemiopsis sp., Pleurobrachia sp.), larvacea (Oikopleura sp.), chaetognatha (Sagitta sp.), and diatom colonies (Chaetoceros socialis).
		On occasion, veliger larvae of Limacina retroversa were found in spawning patches at concentrations exceeding 600/ml within a few centimeters of the air-sea interface.

	Biotoxins, aquatic (marine and freshwater) (EHC 37, 1984)
		As these fish feed on zooplankton but not on dinoflagellates, it has been suggested that the zooplankton, feeding on the dinoflagellates, may act as vectors of PSP.
		In the stomach of herrings from the Bay of Fundy kill, White (1977) was able to identify thecosomatous pteropods (Limacina retroversa), and the stomach contents contained PSP.
		In an experimental study, a similar amount of PSP (21 µg/fish) caused paralysis and death in herrings.

		Despite the substantially lower Calanus abundance in 1998, overall zooplankton biomass levels as revealed by net catches and acoustic indices were comparable between the three years.
		Potential competitors (other copepods, the pteropod Limacina retroversa), and predators (euphausiids, decapods, medusae, and siphonophores) had enhanced biomass and/or numbers.
		This comprehensive data set provides insight into the relationship between far- and near-field effects on C.
