Diagnosis
IDENTIFICATION. Small (less than 1 cm bell height), with a highly sculptured bell and vertical
keyhole-shaped rhopalial niche ostia, lacking the upper and/or lower covering scales typical of
other species. Other conspicuous characters include the pedalial keels being very narrow and the outer keel is decorated with a series of horizontal nematocyst bars; the phacellae comprise a crescent-shaped bundle of cirri which are individually rooted in the floor of the stomach; and
the velarial canals are 2 per octant and paw-like in shape. Furthermore, the exumbrella has four adhesive pads, one over each interradial quadrant of the stomach, though these are not always conspicuous. The gonads grow from the stomach downward, having a somewhat pendant appearance inside the coelenteron. The North Queensland form of C. sivickisi has horizontally elongate, sausage-shaped statoliths. The tentacular nematocysts are of four different types: 1) football-shaped euryteles, 13-19 x 10-12 2) football-shaped isorhizas with full tubules, 16-19 x 10-12 3) round euryteles, 11-12 x 10-11 and 4) long oval isorhizas, 9-11 x 4-6
