草蓆鐘螺屬

草蓆鐘螺屬（學名：Monodonta），是原始腹足目鐘螺科的一屬。
拉馬克於1801年將本屬從林奈的鐘螺屬（Trochus）中分離出來，以草蓆鐘螺（Monodonta labio）為模式種。
本屬的學名直譯就是「單齒螺」，而這名稱也是來自中國大陸的文獻最普遍使用的譯名dzz2002。然而，「單齒螺」這個譯名有歧義：還有另一個螺的屬也可譯作「單齒螺」；但本屬的臺灣譯名「草蓆鐘螺屬」並不會引起歧義，所以本條採取了這個譯名。

**特徵**
本屬通常擁有厚重的圓錐狀螺旋形硬殼，殼表面光滑或有螺旋凸紋，開口外緣內面有褶皺。瓷質的短軸柱堅固、呈膨大圓柱狀、近基部或多或少帶鋸齒狀，齒與基底邊緣之間有方形槽溝紋。殼洞高位開口而寬闊。

**分佈**
從印度洋中西部、中印半島、馬來群島至大洋洲，包括菲律賓、日本、澳洲（北領地、昆士蘭州、西澳大利亞州）等都有本屬的分佈。
