Individual variations of the phospholipid compositions of the organs of arthropods, echinoderms, and tunicates from peter the Great Bay of the Sea of Japan

Individual variations of the phospholipid compositions of the organs of arthropods, echinoderms,... Individual variations in the phospholipid compositions of the organs of marine invertebrates were investigated in the representatives of three phyla: Arthropoda [decapods: Paralithodes camtschaticus (Tilesius, 1815) and Erimacrus isenbeckii (Brandt, 1848)]; Echinodermata [starfishes: Distolasterias nipon (Doderlein, 1902) and Evasterias echinosoma Fisher, 1926]; and Tunicata [ascidians: Halocynthia aurantium (Pallas, 1787), H. roretzi (Drasche, 1884), and Styela clava Herdman, 1881]. The specificity of individual phospholipid variation was shown to be related to the systematic status and functional properties of the organs of marine invertebrates.

Low variation of phospholipid composition was found in the liver, legs, and gills of decapods; in the liver of starfishes; and in the gonads and skin-muscular and gill sacs of ascidians.

Abstract

Individual variations in the phospholipid compositions of the organs of marine invertebrates were investigated in the representatives of three phyla: Arthropoda [decapods: Paralithodes camtschaticus (Tilesius, 1815) and Erimacrus isenbeckii (Brandt, 1848)]; Echinodermata [starfishes: Distolasterias nipon (Doderlein, 1902) and Evasterias echinosoma Fisher, 1926]; and Tunicata [ascidians: Halocynthia aurantium (Pallas, 1787), H. roretzi (Drasche, 1884), and Styela clava Herdman, 1881]. The specificity of individual phospholipid variation was shown to be related to the systematic status and functional properties of the organs of marine invertebrates. Phosphatidylcholine and phosphatidylethanolamine were the least variable. Low variation of phospholipid composition was found in the liver, legs, and gills of decapods; in the liver of starfishes; and in the gonads and skin-muscular and gill sacs of ascidians. The contents of ceramide aminoethylphosphonate (CAEP) and phosphatidylglycerol (PG) showed the highest variation. These phospholipids were found but not in all individuals or organs studied. After 7 days of starvation, CAEP completely disappeared from the organs of the animals; thus, we suggest its exogenous origin.
