Their charges are susceptible to intestinal nematode worms which cause them to waste away and can, in severe cases, kill them.

他们的羊群容易受到肠道线虫的影响，这些蠕虫会使它们日渐消瘦，在严重的情况下，会令它们死亡。

When people eat this fish, we interrupt this natural cycle, and the nematode worm larvae can take up residence inside our throat, stomach, or intestinal lining instead.

线虫是海洋中数量最多的多细胞生物之一，其他种类的蠕虫已经移居陆地， 有些甚至侵入我们自己的身体！

Until now, the production of connectomes has been limited to those of simpler organisms such as the nematode worm, whose brains have hundreds of neurons and in which complex behaviour has not yet been observed.

到目前为止， 连接体的产生仅限于线虫等较简单的生物体，线虫的大脑有数百个神经元， 其复杂行为尚未被观察到。
