Rhabdastrella globostellata

Lafi, F. F., Garson, M. J., and Fuerst, J. A. (2005). Culturable bacterial symbionts isolated from two distinct sponge species (Pseudoceratina clavata and Rhabdastrella globostellata) from the great barrier reef display similar phylogenetic diversity. Microb. Ecol. 50, 213-220. 

Many chemical data relate to the species Jaspis stellifera which is now regarded as the species Rhabdastrella globostellata (see Systema Porifera, Hooper and Van Soest, 2002a). 

Globostelletins A-I and rhabdastins A-G are two new series of isomalabaricane derivatives isolated from the species Rhabdastrella globostellata collected in China (Hainan Island) and in Japan (Amami-oshima Island), respectively. Rhabdastatins are only weakly cytotoxic and globostelletins display no cytotoxic noticeable activity (Li et al., 2010a Hirashima et al., 2010). 

The first example of an a-ribopyranoside of stelliferin was isolated in 2001 from Geodia obostellifera, harvested in Fiji at a depth of 5 m, and also foimd in 2006 in Rhabdastrella globostellata, also from Fiji at 12 m (Tabudravu and Jaspars, 2001 Clement et al., 2006).
