当你漫步在红海海滨的时候,你会看到,在近海浅滩的海底上,这里一堆,那里一丛,长着许多“海草”,它那细长的“茎”从海底向上延伸,在水中徐徐摆动。可是,当你走近一看,就会惊奇地发现,每一条“海草茎”的上端都有一对大眼晴,一张嘴,两片鳃盖和很小的胸鳍。如果有什么东西突然扰乱了海水的平静,这些“海草”就会一下子消失得无影无踪,连在海底沙上都不留下 As you walk along the Red Sea coast, you will see that on the sea floor near the shallows of the sea, there is a pile, there is a cluster there, and there are many “seagrass”. Its long “stems” extend upward from the bottom of the sea. The water slowly swings. However, as you approach, you will be amazed to discover that each “seaweed stem” has a pair of large eyes, a mouth, two lids, and a small pectoral fin. If something suddenly disturbs the calm of seawater, these “seagrass” will disappear all at once, leaving no traces on the seabed sand.
