貉藻 Droseraceae 性狀： 食蟲植物，沉水性水草。一種生長在貧瘠環境下的水生食蟲植物，也能漂浮生長，及從葉腋綻放單生小白花，喜歡較高水溫，在低溫下會休眠。它的葉子不是我們印象中的那種扁平片狀的葉子，而是變成具有類似捕蠅草那種夾子狀的捕蟲器之貝殼狀運動構造，所以有「水中的捕蠅草」的別稱。通常為 6-8 枚輪生葉，有柄及葉鬚，黃綠色。當有水蚤或其他水生昆蟲 接觸到它的葉面時，整片葉子會立即由兩翼合併起來，將水蚤夾在葉中，等到水蚤死亡，隨即分泌酵素分解屍體，從而靠吸收養份維生。不過它也能進行光合作用，及依賴吸收水中的無機養份生長，所以也能栽培在水族缸中供人欣賞，不過育成較為困難。栽培上需要弱酸性的水質，充足的光照，在適當環境下也可能變成紅色的水草。
