puff ball sponge Oceanapia sagittaria* Family Phloeodictyidae updated Oct 2019 Where seen? This small pink puff is sometimes seen on some of our shores among coral rubble. It's just the tip of an enormous buried sponge! Features: Small delicate prickly ball about 1-2cm in diameter, on a short conical stem (called the capitate structure). The ball has fine sheets between the prickles. Seen singly but sometimes a few seen near one another growing on coral rubble. This puffy fluff is just a tiny part of the sponge. The bulk of the sponge is actually buried! The main sponge is bulbous and spherical. Colour usually a deep maroon to bright pink. The capitate structure is where the water is 'exhaled' from the sponge, and also where propagules (new sponges) are dispersed. |
