Online biodiversity images for Axinella polycapella (field observations and preserved specimens) typically depict an erect sponge growth form with tufted/branching projections and a fibrous to porous external surface consistent with demosponges.
A study links Axinella polycapella to hydroxyhydroquinone (1,2,4-trihydroxybenzene), discussing its antimicrobial relevance in this sponge-associated context. The work further describes an obligately anaerobic fermenting bacterium capable of using hydroxyhydroquinone as its sole carbon and energy source. (The bacterium is not a sponge taxon.)[2]
GBIF treats Axinella polycapella de Laubenfels, 1953 as an accepted species name.[3]
