sponge green seaweed Cladophoropsis vaucheriaeformis* Family Siphonocladaceae updated Aug 10 Where seen? This woolly branching seaweed is often seen on many of our Southern shores, growing on coral rubble. Features: The entire organism can be about 20-30cm across, with 'stems' about 1-2cm wide. Each 'stem' is made up of fine, branched filaments that are packed together to form structures that feel woolly, velvety, spongey or felt-like. The 'stems' are smooth and do not have obvious holes in them, especially when the sponge is out of water. Light to dark green. This organism is actually a symbiotic combination of an algae (Cladophoropsis vaucheriaeformis) and a sponge (Halichondria cartilaginea)! The sponge cells and spicules are intertwined with the algae. Sometimes confused with the Holey sponge seaweed (Ceratodictyon sp.) which has 'holes' along the 'stems'. It is a red seaweed which also has a symbiotic relationship with another kind of sponge. |
