Astralium rotularium, common name the rotary star shell or the knob star shell, is a species of sea snail, a marine gastropod mollusk in the family Turbinidae, the turban snails.[2][3]
Description
The size of the shell varies between 25 mm and 50 mm. The white, subdepressed, imperforate shell has a conoid shape. The spire is subacute. The six whorls are obliquely finely costulate with numerous prominent imbricating laterally compressed plicae at the sutures. The body whorl is carinated with plicate-nodose carina. The base of the shell is convex, squamosely concentrically lirate. The white columella is arcuate, not dentate. The aperture is oblique.[4]
Distribution
This marine species is endemic to Australia and occurs off the Northern Territory, Queensland and Western Australia
