The composition of carotenoids was investigated in tissues of the colonial sea squirt Botryllus schlosseri (Pallas, 1766), which inhabits the Crimean coast near the city of Sevastopol. The total carotenoid amount of B. schlosseri was found to be 8.7 ± 4.6 mg/100 g of wet weight. Eleven carotenoids, that is, ß-carotene, 7,8-didehydroastaxanthin, 7,8,7',8',-tetradehydroastaxanthin, pectenolone, 4-ketoalloxanthin, diatoxanthin, diadinoxanthin, fucoxanthin, astaxanthin, alloxanthin, and halocynthiax
