4.2. Animal Material

The sponge sample (1.3 kg) was collected by SCUBA diving at a depth of 7–12 m near Cham Island (15°54.3′ N, 108°31.9′ E) in the Vietnamese waters of the South China Sea during the 38th cruise of R/V “Academik Oparin” in May 2010. The species was previously identified and described as Stelletta sp. [14]. According to an extensive revision of sponge specimens provided by Dr. Paco Cárdenas (Department of Pharmaceutical Biosciences, Uppsala University, Sweden), this sponge was re-identified as Rhabdastrella globostellata [12]. A voucher specimen (PIBOC O38-301) has been deposited at the collection of marine invertebrates of the G.B. Elyakov Pacific Institute of Bioorganic Chemistry FEB RAS, Vladivostok, Russia.
