It differs from all other Sabellidae in having a calcareous tube and spinose setae. Only one living species, ''G. piloseta'', is known from Lizard Island, Great Barrier Reef, Australia. The oldest fossils of ''Glomerula'' are known from the Early Jurassic and their tube microstructure has remained unchanged since then. == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Glomerula」の詳細全文を読む スポンサード リンク
