“…While the mouthparts of species of the genus Thysanoessa are suited for filter-feeding, capture of copepods through the rapid lateral spreading of the thoracic Limbs has been described for T. longipes and T. inerrnis (Mauchline & Fisher 1969). The lipid composition of Thysanoessa macrura, which is very different from that of other euphausiids, supports this observation (Reinhardt & Van Vleet 1986). T. macrura stores large amounts of wax esters and phospholipids, which are presumably used as energy reserves during winrer and ior gonad deveiopment in spring (Hagen 1988).…”

ABSTRACT-Lipid content and lipid class composition of Euphausia superba were studied at different levels for populations and individuals sampled in the Indian sector of the Antarctic Ocean. Strong siteto-site var~ability was recorded whlch could only partially be related to sex or development stage differences. Three groups of stations could be d~fferentiated. Northern stations were characterized by 'high lipid-high triglyceride' content, western and eastern locations by 'high lipid-high phosphatidyl choline' content and southern areas by 'low lipid-high phosphatidyl ethanolamine/glycolipid' content. Such variability was likely related to advected populations h a v~n g spent variable lengths of time in the area studled. Lipid content and class among organs were studied in 5 body fractions: abdomen, stomach, digestive gland, gonad and fat body. In absolute terms, the hi.ghest concentrations were observed in the ovaries of mature females and the abdomens of the other stages. In relative terms ("'0 dry weight), the digestive gland displayed the highest level, except in mature females. Distribution varied with stages, with low triglyceride levels in abdomen tissues of most stages and in the fat body and stomach fractions of subadults. H~g h triglyceride levels were recorded In the other fractions for post spawning females and males, as well as in the fat body fraction for mature females and in subadult gonads. A reverse pattern was observed for the relative content of phosphatidyl choline. Phosphatidyl ethanolamine showed maximum values in the abdomen and the gonad. Glycolipid percentages were maximum in the abdomen, suggesting a structural role. The roles of the different lipid classes are discussed w~t h respect to the function of the organ.
