Daisy sponge
Coelocarteria singaporensis*
Family Isodictyidae
updated Oct 2016
Where seen? This strange sponge is seen on many of our southern shores, growing on and among coral rubble and on sandy areas near the reef edge. It was described from Singapore, hence its species name.

Features:
15-20cm in diameter. There is usually one or two large hollow cones (to 2cm in diameter), encircled by upright long 'fingers' (up to 15cm tall). These fingers are generally unbranched with flattened or rounded tips, and they don't have any large holes. With some imagination, it does resemble a daisy, doesn't it? There may be creeping buried 'rhizomes' extending along the ground from the sponge with fingers sticking up from these horizontal stems. Colours include bright yellow, brownish, greenish and black.

Sometimes covered with tiny Spinoid worms.
Another sponge species of a different family (Oceanapia sp., Family Phloeodictyidae) can look very similar and the two kinds of sponges are difficult to tell apart in the field.

This is possibly Oceanapia sp.
and NOT a Daisy sponge

*Sponge species are difficult to positively identify without close examination.
On this website, they are grouped by external features for convenience of display.
