Well, one simple way is to follow what John Mew calls the tropic premise: “Rest the tongue on the palate with the lips sealed and the teeth in light contact for four to eight hours a day.”

一个简单办法就是遵循 John Mew 所谓的“向性处所”：“将舌头顶在上颚，轻轻闭紧嘴唇和牙齿，每天4~8个小时。”

And the mucus has another function: It helps the fish’s lips seal shut around the lumpy coral, which helps it suck in one particularly tasty part: the polyps’ own mucus, plus some flesh chunks.

粘液还有另一个功能： 它帮助鱼的嘴唇密封住块状珊瑚，这有助于它吸入一个特别美味的部分： 珊瑚虫自己的粘液和一些肉块。
