sea pen

同根派生

The sea had eaten away much of the shore.
海浪对海岸侵蚀得厉害。
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，在文献纪载方面，即使一些具商业价值但不大普遍的鱼类，以及生长在本港极北地区的珊瑚品种，也少有纪载，更遑论成千上万不太为人熟悉的蠕虫、海胆、海星、雌鹄及更微细的浮游生物。
In no minute did the sea run amuck.
倾刻间海上刮起了大风暴。
The storm heaved the sea into mountainous waves.
风暴在海面上掀起万丈波涛。
The sea have erode the cliff face over the years.
海水经年累月冲刷著峭壁的表面。
