Olive green stalked cup demosponge

Cymbastela stipitata (Bergquist & Tizard, 1967) (OTU QM0005) [Demospongiae, Halichondrida, Axinellidae] This species is thought to be endemic to northern Australia. It is characteristically found in high energy sedimented environments such as reef flats and shallow subtidal reefs. Its green colouration is probably due to the chlorophyll pigments from its resident (symbiotic) cyanobacteria.
