The carotenoid composition has been analyzed in tissues of the marine clam mollusk Polititapes aureus (Gmelin, 1791), which dwells in the top part of Kazachya Bay near Sevastopol on the Black Sea. The dynamics of the total carotenoid concentration in mollusk soft tissues follows a seasonal annual cycle, with the maximum concentration (1.7 ± 0.47 mg/100 g of raw tissue) in the spring, at the beginning of March. This concentration declined to 0.41 ± 0.10 mg/100 g of raw tissue by the summer and re
