第45课 一种叫“鳎”的比目鱼
Does your mother ever give you fish for dinner? If so, I dare say that you have eaten the fish called the sole. From the shape of its body it is called a flat fish.
小朋友, 妈妈给你吃过鱼吗? 要是吃过, 我敢说你一定吃过一种叫“鳎”的鱼。因为它的身体是平的, 所以也叫“板鱼”, 学名是“比目鱼”。
The two sides of the sole are of different colours. The one side is nearly white. That is the side that rests on the ground when the fish lies at the bottom of the sea. The other or upper side is of a brown colour, with dark spots.
比目鱼的身体两边颜色不一样。一边差不多是白色的, 比目鱼躺在海底的时候, 就用这一边贴着地面。另一边, 也就是上边, 是褐色的, 长着深色的斑点。
You must not think that the dark upper side is the back of the fish. Most fishes swim upright in the water, and so does the sole when it is quite young. But as it grows it spends its time lying on its left side on the sandy bottom of the sea. Then this side turns white, and the right side dark.
可不要以为, 这深色的上边是鱼的后背!大多数鱼在水里是左右平衡地游泳的, 比目鱼在很小的时候也这么游泳, 但是长大的时候, 它就有越来越多的时间, 用身体的左边躺在海底沙子上。这一面就变成了白色, 身体右边就变成了深色。
Now in this position its left eye could be of no use to it. So a very wonderful thing happens. The left eye of the young sole moves slowly round its head, until both eyes are on the upper or right side of the fish.
这时候, 左眼的位置就没有用了, 于是发生了一件非常奇妙的事。小比目鱼的左眼慢慢地绕过脑袋, 移了过来, 最后, 两只眼睛都到了鱼的上边, 也就是右半边。
The sole has a very small mouth, and only the lower jaw has any teeth. Look at its fins. There is a long fin on each side, reaching from the head right along to the tail.
比目鱼的嘴非常小, 只有下腭才有牙。看看比目鱼的鳍, 身体两边各有一条很长的鳍, 从脑袋一直延伸到尾巴。
