Predatory mollusc clione demonstrates its feeding response in the presence of its prey -- shelled mollusc limacina credit: dr tigran norekian. Introduction the gymnosomatous pteropod clione limacina (phipps) feeds throughout its post- veliger life exclusively on two closely related species of thecosomatous pteropods, spiratella (limacina) retroversa (fleming) and s', helicina (phipps) (lalli, 1970 conover & lalli, 1972. The gymnosomatous pteropod clione limacina (phipps) assimilated carbon from its prey spiratella retroversa (fleming) with greater than 90 % efficiency and with nearly 100 % efficiency for nitrogen the respiratory rate of clione was found to vary with locality and season, but the weight exponent did not differ significantly nor was it affected by temperature.
Sea angels are gelatinous, mostly transparent, and very small, with the largest species (clione limacina) reaching 5 cm c limacina is a polar species those found in warmer waters are far smaller some species of sea angels feed exclusively on sea butterflies the angels have terminal mouths with the radula common to mollusks, and tentacles to grasp their prey, sometimes with suckers similar to cephalopods. The gymnosomatous pteropod clione limacina (phipps) there was some tendency for the animals to defaecate after eating, but this behaviour was not sufficiently predictable to facilitate collection of faecal material high conversion efficiency shown by clione is another beneficial consequence of its extremely specialized food habits.

Clione limacina inhabits both the epipelagic and mesopelagic regions of the water column feeding habits adults feed in a predator-prey relationship almost exclusively on the sea butterflies of the genus limacina: on limacina helicina and on limacina retroversa the feeding process of clione limacina is somewhat extraordinary the buccal (mouth) apparatus consists of three pairs of buccal cones. The feeding specialization of clione is reflected in numerous adaptations because even the early polytrochous larvae of clione feed on limacina, the life cycles of predator and prey are necessarily closely synchronized the feeding behavior of c limacina is described in detail by lalli and gilmer (1989) and hermans and satterlie (1992. Clione limacina is a relatively common non-shelled (gymnosomatous) pteropod and appears to feed exclusively on species of the shelled (thecosomatous) pteropod genus spiratella it grows to about 25mm in length lalli (1970) studied its feeding behaviour in laboratory studies, which showed how the unique feeding apparatus of these gymnosomatous pteropods functions.

Sea angels, clione limacina and paedoclione doliiformis, are small, floating sea slugs belonging to gastropoda, and their gonads are a bright orange-red color sea angels feed exclusively on a small herbivorous sea snail, limacina helicina carotenoids in c limacina, p doliiformis, and l helicina were investigated for comparative biochemical points of view β-carotene, zeaxanthin, and. Clione limacina limacina forma limacina is a protandric hermaphrodite copulation in the present species , in all probability this forma , was described by boas (1886a) two copulating specimens are found with the ventral sides turned towards each other with the heads in the same position.
Clione limacina is itself eaten by fish and sea birds clione limacina was previously considered to have a bipolar distribution but gilmer & lalli (1990) show many internal and external differences between northern and southern hemisphere populations and consider the southern populations should be considered a distinct species, c antarctica (smith, 1902. Sea angels are gelatinous, mostly transparent, and very small, with the largest species (clione limacina) reaching 5 cm c limacina is a polar species those found in warmer waters are far smaller.
Sea angel: clione limacina (phipps, 1774) the most common naked pteropod of arctic waters size larvae ~ 015 mm adults up to 4 cm color & characteristics barrel-shaped body with paddle-like lateral wings.
Clione limacina is a prey of planktonic feeders, such as the baleen whales, which historically led to sailors naming it whale-food some fishes are also its predators  for example, the chum salmon, oncorhynchus keta , is a major predator of sea angels. Feeding habits they produce large they eat the web with the captured prey and then re-reproduce a web net the web is large and spherical and it is difficult to see during the day millar, r m (2001) lipids and fatty acids in clione limacina and limacina helicina in svalbard waters and the arctic ocean: trophic implications polar. Because even the early polytrochous larvae of clione feed on limacina, the life cycles of predator and prey are necessarily closely synchronized the feeding behavior of c limacina is described in detail by lalli and gilmer (1989) and hermans and satterlie (1992.
