比目鱼

发布时间：2020-09-13 编辑：查字典英语网小编

今天我看了一本书叫《海洋动物》里面有一个故事是说比目鱼的眼睛为什么长在身体一侧。

Today, I read a book called "marine animals". There is a story about why the eyes of flounder grow on one side of the body.

原来比目鱼长期生活在海底世界身体平躺着下侧的那只眼睛就用不上了，只有上侧能观察，为了需要，下侧的眼睛就渐渐移到上面来了。这种移到现象是从幼鱼期开始的，比目鱼将卵产在海面上层，鱼卵漂浮在海面上，再孵化成幼鱼。幼鱼长到了3厘米，头部一侧的眼睛就开始向头顶移动了。经过一段时间，比目鱼的双眼就移到一侧。

It turns out that the lower eye of the flounder, which has been living in the underwater world for a long time, can't be used. Only the upper side can observe. For the sake of need, the lower eye gradually moves to the upper side. This migration phenomenon starts from the juvenile stage, when the flatfish lays its eggs on the upper layer of the sea, floats the eggs on the sea surface, and then hatches them into juveniles. When the larvae grow to 3cm, the eyes on one side of the head begin to move towards the top of the head. After a while, the eyes of the flounder moved to one side.

读完了这个故事我的收获太多了。

After reading this story, I got too much.
