文昌魚是比魚类还要原始的动物,它是下等动物和高等动物之間的桥樑。就是我們人类从進化歷史上来說,也經过类似文昌魚的这个階段。在我們研究生物進化过程的時候,文昌魚是值得注意的一种动物。这种有着歷史意义的动物,現在在祖國的海边上——夏門和青島,还在生活着。厦門文昌魚的產量,每年达到35噸之多,它是一种良好的食物。文昌魚是一种一寸多長、兩端尖的魚形动物。拿一条小魚来和它比較,就能够使我們很容易了解文昌魚的一般構造。
Amphioxus is an animal more primitive than fish. It is a bridge between lower animals and higher animals. It is that we humans have also passed this phase of the amphioxus from the evolutionary history. In our study of the biological evolution process, amphioxus is an animal worth noting. This historic animal is now living in the sea of the motherland - Xiamen and Qingdao. The output of Xiamen Wenchang fish is as high as 35 tons per year. It is a good food. Amphioxus is a fish-shaped animal that is more than one inch long and has sharp ends. Taking a small fish to compare with it can make it easy for us to understand the general structure of the amphioxus.
