sea pen

同根派生

The sea had eaten away much of the shore.
海浪對海岸侵蝕得厲害。
The less-common commercial fish and many corals that reach the northernmost extent of their range in Hong Kong remain poorly documented,not to mention the myriad of less familiar worms,urchins,starfish,sea pens and the more microscopicplanktonic forms.
然而，在文獻紀載方麪，即使一些具商業價值但不大普遍的魚類，以及生長在本港極北地區的珊瑚品種，也少有紀載，更遑論成千上萬不太爲人熟悉的蠕蟲、海膽、海星、雌鵠及更微細的浮遊生物。
In no minute did the sea run amuck.
傾刻間海上刮起了大風暴。
The storm heaved the sea into mountainous waves.
風暴在海麪上掀起萬丈波濤。
The sea have erode the cliff face over the years.
海水經年累月沖刷著峭壁的表麪。
