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

答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感觉感受器构成。

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

侧线也可以感知和探测压，和物体。

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

侧线指是沿着鱼皮表面特殊气管中一排特殊细胞。

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。

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

就像鱼侧线一样，这些扮演着动力天线角色传感器接收周信号。

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详细信息以及它们如何使用它来感知自己环境。

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.

它和其他生两栖动物一样，配备了一个惊人装置，告诉我们它生活在中：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，动物需要有敏锐感觉。鱼和一些贝壳类动物有敏锐眼睛，几乎所有动物对触觉都很敏感。鱼依靠侧线来察觉中活动。
