求翻译：　　走出隧道，就看到了人鱼表演。我看呆了，一位潜水员竟引出了一条魔鬼鱼，跟它载歌载舞。别看魔鬼鱼肚子扁，饭量还真不小，潜水员给它条小黄鱼，它一口就吞掉了。是什么意思？

　　Out of the tunnel, sees the mermaid show. I stayed, one diver leads a devil fish, singing and dancing with it. While a devil fish stomach flat, really not a small appetite, pseudosciaena polyactis divers to it, it will devour.
