Resumo: 	Sampling was made in May of 1974, and in the studied region of the Ligurian sea at a 115-640 m depth five biotopes were distinguished: coarse and fine sands, lythothamnium, aleuritic and pelitic muds. Various biotopes were analysed for systematic composition and quantitative distribution of macrozoobenthos. Biotopes of lythothamnium and coarse sand are found to have the highest indices of macrobenthos number and biomass (767 specimen/m2; 76.7 g/m2 and 127 specimen/m2; 22.0 g/m2, respectively). The pelitic mud biotope is featured by a small number (58 specimen/m2) and biomass (0.99 g/m2). Average numbers of macrobenthos in the region under study are 233 specimen/m2 with average biomass 21.0 g/m2. The number of meiofauna is 25 times as high as that of macrobenthos. Its average amount is  5802 specimen/m2, biomass - 0.122 g/m2. Free-living nematodes and Polychaeta are dominating meiofauna groups. Biotopes of fine sand, lythothamnium and aleuritic mud contain almost equal amounts of meiobenthos (7539-7968 specimen/m2) with biomass being 0.091, 0.253 and 0.127 g/m2, respectively. Meiobenthos number in the coarse sand biotope is twice lower and in the pelitic mud biotope - thrice as low as those previously mentioned.
