Proximate composition, sterol and -tocopherol (-Toc) contents of 35 species of marine invertebrates (13 species of Bivalvia, 10 species of Gastropoda, 4 species of Cephalopoda, 4 species of Crustacea, 2 species of Ascidacea and 2 species of Holothuroidea), which caught off the coast of Tongyeong of the Southern sea (Nam-Hae), Korea, were determined. Protein content showed relatively high level in herbivorous (seaweed feeder) and carnivorous species such as Gastropoda (), Crustacea () and Cephalopoda (), but showed low in plankton feeder and mud swallow such as Bivalvia (), Ascidacea () and Holothuroidea (). Total lipid (TL) content was low in most marine invertebrates, ranged from (blue colored sea cucumbers) to (sea squirts). Ascidacea contained the largest amount of TL in all samples, while Holothuroidea contained the smallest amount of TL, and other classes contained about of TL. Carbohydrates was rich in plankton feeder and Herbivorous species (seaweed feeder) such as Ascidacea (), Bivalvia () and Gastropoda (), while poor in carnivorous species such as Crustacea () and Cephalopoda (). Moisture content was highest in Holothuroidea () and the lowest in Gastropoda (): There were negative correlations between moisture and protein content, or TL, between protein and TL content; y= -0.8716x+184.452 (r=-0.87, p (r=-0.55, P(r=-0.42, P30.0mg)>Bivalvia (12135.0mg)>Gastropoda (11820.0mg)>Crustacea (11631.0mg)>Ascidacea (78.02.00 mg)>Holothuroidea(62.08.00 mg). Crustacea contained 12 mg -Toc/100 g edible portion whereas other classes contained trace or less than 1 mg/100 g of edible portion.
