第90篇14600英文核心词汇学习

1

今天的英国儿童新闻，要和大家分享一种神奇的sea slug，这种sea slug可以自己把自己的头和身体分开。研究人员说，可能这种sea slug的身体里有某种有害的parasite（寄生虫），所以他们要抛弃自己的旧身体。

除了儿童新闻，英国的The Guardian和BBC都报道了这种神奇的生物。

Scientists in Japan have discovered that certain types of sea slug have the ability to remove their head and grow a whole new body! 

“We were surprised to see the head moving just after autotomy.” 

Autotomy is when a creature can lose part of its body. The most well-known examples are probably the lizards that can 'drop’ their tail if threatened, then grow one back later.

That’s pretty amazing in itself, but the sea slug’s ability is on another level. Once removed, the head can move around on its own. Within a few weeks, it can grow a whole new body, complete with heart and other internal organs. （内脏）

 

It’s not known why the slugs detach their head from their body. One reason could be a way of removing a parasite (something harmful that lives on or inside something else.)
