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，物需要有敏锐感觉。和一些贝壳类物有敏锐眼睛，几乎所有物对触觉都很敏感。依靠线来察觉中活。

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

线也可以感知和探测压，流和物体。

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

就像线一样，些扮演力天线角色传感器接收周围流信号。

The lateral line consists of sensory receptors called neuro masts.

线由叫做神经桅杆感觉感受器构成。

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线详细信息以及它们如何使用它来感知自己环境。

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

答案是还有另一个感觉器官，叫做线。

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

线指是沿皮表面特殊气管中一排特殊细胞。

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，它和其他生两栖物一样，配备了一种令人惊叹系统，告诉我们它生活在中：线系统。

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.

你会看到更多三线防守，但我意思不是指三个防守前线球员，然后两边仍然各有外线卫。

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

所以我会像外线卫和强力安全卫那样，冲上去猛烈撞击，就像我渴望那样。

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，在主线路旁边设有线，列车可以在里停靠避让。
