蛆管螺屬

蛆管螺屬（Caecum）是微小海螺的一屬、海洋腹足綱的微型軟體動物，屬於蛆管螺科，也是蛆管螺科的模式屬。

## 分布

這個屬在全世界的溫暖海洋（溫帶海洋性氣候地域）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，其胚螺仍然是螺旋狀生長的，但其次生螺層（teleoconch）只彎成一條彎曲的角狀管；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、帶螺旋的角質螺厴掩蓋。螺殼上的裝飾若不是平滑，就是有大量密集的環形脊線組成。

## 食性

本屬物種以沙粒或鵝卵石上的單細胞生物為食。
