蛆管螺屬

蛆管螺屬（）是微小海螺的一属、海洋腹足纲的微型软体动物，属于蛆管螺科，也是蛆管螺科的模式屬。

分布
這個屬在全世界的溫暖海洋（温带海洋性气候地域）出現。大部分物種生活在海綿、珊瑚礁的沙地或海灣，在海灣及潟湖淺水區的海藻床帶，例如常見的美麗Caecum pulchellum。不過牠們微小的體型亦使之容易被忽略。部分物種被認為是不常見的，這種評估可能是缺乏適當抽樣的結果。

 形態描述 
如同其他蛆管螺科物種，蛆管螺屬的體型微小，殼長介乎2 mm到6 mm；螺殼顏色白到淺黃，而且大多數也薄得可以透光。雖然，其仍然是螺旋狀生長的，但其次生螺层（）只彎成一條弯曲的角狀管；而其胚螺亦與其他蛆管螺亞科物種一樣，在成長時脫落，使整個螺殼變成了一個簡單的筒狀。

螺管在脫落了胚螺的一端會有一個鈣質的分泌物永久把螺殼封閉；而殼另一端的殼口有圓形、帶螺旋的角質螺厣掩蓋。螺殼上的裝飾若不是平滑，就是有大量密集的环形脊线组成。

食性
本屬物種以沙粒或鹅卵石上的单细胞生物为食。
