The answer is that fish have another sensory organ called the lateral line.

案是鱼还有另一个感觉器官，叫做侧线。

The lateral line consists of sensory receptors called neuro masts.

侧线由叫做神经桅杆的感觉感受器构成。

The lateral line can also sense and detect water pressure, currents, objects.

侧线也可感知和探测水压，水流和物体。

A lateral line is a row of special cells inside a special canal along the surface of the fish's skin.

侧线的是沿着鱼皮表面的特殊气管中的一排特殊的细胞。

And there, in the single-line siding, was a railroad handcar.

在那儿，在单线侧线上，有一辆铁路手推车。

And tracks were built to accommodate this, with sidings alongside the main line where trains can pull over.

而且轨道也是为此建造的，在主线路旁边设有侧线，列车可在这里停靠避让。

Known as the “lateral line, ”these sensors apparently act like a hydrodynamic antenna, picking up signals about the flow of water around them.

就像鱼的侧线一样，这些扮演着水动力天线角色的传感器接收周围水流的信。

So I would play like outside linebacker strong safety like I'm coming to lay down the boom like I want to.

所我会像外侧线卫和强力安全卫那样，冲上去猛烈撞击，就像我渴望的那样。

And then I said first of all, and I went into detail about the lateral line and how they use that to sense their, their environment.

然后我说了首先，然后我继续谈论了有关侧线的详细信息及它们如何使用它来感知自己的环境。

You get a lot more three down fronts and I don't mean three defensive linemen and then you still have your two outside linebackers on the edge.

你会看到更多的三线防守，但我的意思不是三个防守前线球员，然后两边仍然各有外侧线卫。

And it, along with other aquatic amphibians, was equipped with an an amazing apparatus that tells us that it lived in the water: a lateral line system.

而且，它和其他水生两栖动物一样，配备了一种令人惊叹的系统，告诉我们它生活在水中：侧线系统。

In order to stay alive, animals need to have keen senses. Fish and some shellfish have sharp eyes. Almost all animals are sensitive to touch. Fish detect movements in the water by means of their lateral lines.

为了生存下来，动物需要有敏锐的感觉。鱼和一些贝壳类动物有敏锐的眼睛，几乎所有的动物对触觉都很敏感。鱼依靠侧线来察觉水中的活动。
