WebResults showed significant bleaching (50–80%) in the host Z. sansibaricus, resulting from a decrease in symbiotic zooxanthellae count, cell density, chl a and chl c content. This suggests the role of β-sitosterol as allelochemical of the sponge in preventing the overgrowth of aggressive Z. sansibaricus, possibly by affecting its symbionts.
