It appears that the bichir's anatomy is as plastic as their behaviour.

看来双子犬的身体结构和它们的行为一样具有可塑性。

Standen thought that she would try raising bichirs on land.

Standen 认为她会尝试在陆地上饲养比奇鸟。

This kind of makes sense if you look at air-breathing fish today, like the lungfish and bichir.

如果你今天看一下会呼吸空气的 鱼，比如肺鱼和比希尔鱼，这种说法是有道理的。

Standen's bichirs grew up in a decidedly damp but totally terrestrial environment.

Standen 的双颊鸟生长在一个绝对潮湿但完全是陆地的环境中。

This suggests that bichirs have the ability to modify their behaviour in response to their environment, a concept called plasticity.

这表明双子星有能力根据环境改变自己的行为，这一概念称为可塑性。

That's an important clue, because this angle creates a more direct path for air to travel to the bichir's lungs.

这是一个重要的线索，因为这个角度为空气创造了一条更直接的路径，让空气能够进入双管齐尔的肺部。

Bichirs, unusually among fish, actually have lungs as well as gills, so they can breathe air.

Bichirs，在鱼类中不同寻常，实际上有肺和鳃，所以它们可以呼吸空气。

She and her team set up some high-speed cameras, placed the bichirs on a stage and let them go.

她和她的团队设置了一些高速摄影机，将比奇鸟放在舞台上，然后让它们离开。

In this way, it kind of resembles the bichir, which uses its head-hole to breathe air from the surface of the water.

这样一来， 它有点像双鱼，它用它的头孔从水面呼吸空气。

When Standen examined the skeletons of her land-living bichirs, she found that their muscles and bones had changed as they adapted to walking.

当斯坦登检查她生活在陆地上的比奇鸟的骨骼时，她发现它们的肌肉和骨骼在适应行走时发生了变化。

They compared their walking abilities with those of bichirs raised more traditionally, you know, in water, and they saw some differences – subtle but distinct.

他们将它们的行走能力与传统上在水中饲养的比奇尔的行走能力进行了比较，他们发现了一些差异——细微但明显。

In both Ichthyostega and Tiktaalik, that hole is much bigger, is closer to the back of the skull, and sits at an angle, just like it does in the bichir.

在 Ichthyostega 和 Tiktaalik 中， 那个洞要大得多，更靠近头骨的后部，并且呈一定角度， 就像在双鱼中一样。

And in one of these fish -- the bichir from Africa -- the hole is bigger, and sits on the top of its skull, farther back, kind of like a blowhole.

其中一种鱼——来自非洲的比奇鱼——的孔更大，位于它头骨的顶部， 更靠后，有点像气孔。
