''Rosella'' is a genus of glass sponges in the family Rossellidae. It is found in the Antarctic and sub-Antarctic regions. Description Species are thick-walled saccular sponges. Calycocomes (six rayed spicules with secondary rays emanating from a solid calyx) are always present.

Secondary rays end as small discs) and microdiscohexasters (smaller forms of mesodiscohexasters). Dermalia (outer spicules of any size class) are usually pentactines, sometimes with stauractines (cross-like spicules with four perpendicular rays) and hexactines.
