However, the subject might also be a chimpanzee learning to use symbols to communicate, a white rat navigating a maze, or a sea slug responding to a danger signal.(然而，其主題也可以是學(xué)習(xí)使用符號(hào)進(jìn)行交流的黑腥腥、在迷宮中航行的白鼠或是一只對(duì)危險(xiǎn)信號(hào)做出反應(yīng)的海參。)

There are over 3,000 known species of these colorful sea slug relatives and new ones are discovered nearly every day.(已知的彩色海參類動(dòng)物超過(guò)了3000多種，而且?guī)缀趺恳惶炀涂梢园l(fā)現(xiàn)一些新品種。)

Hence, an isolated piece of tissue removed from an organism-for example, the eye of a sea slug-will maintain its own daily rhythm but will quickly adopt that of the whole organism when restored to it.(因此，一個(gè)被隔離的組織的一部分被從一個(gè)集體中移走—例如，海蛤蝓的眼睛—組織還會(huì)保持它自己的日常節(jié)奏但是當(dāng)恢復(fù)到整個(gè)集體中時(shí)會(huì)采用機(jī)體的節(jié)奏。)

Once the sea slug has eaten enough algae, and gained enough plastids, it can live off just sunlight for up to nine months.(一旦海蛤蝓吃飽了海藻，儲(chǔ)備夠了葉綠體，它能僅僅靠陽(yáng)光就能生活最多9個(gè)月。)

And so far, this green sea slug is the only known animal that can be truly considered solar-powered, although some animals do exhibit some plant-like behaviors.(到目前為止，這種綠色的海參是唯一一種真正被認(rèn)為是太陽(yáng)能驅(qū)動(dòng)的動(dòng)物，盡管有些動(dòng)物確實(shí)表現(xiàn)出一些植物般的行為。)

They think that it could be a huge, unknown kind of sea slug.(他們認(rèn)為“尼西”可能是一種龐大的、還不為人類所知的海蛞蝓。)

This is a solar-powered sea slug.(這是太陽(yáng)能海蛞蝓。)

So a sea slug could shape its body into the one, two, three or more humps that different people say they have seen.(因此，像不同的人所說(shuō)的那樣，海蛞蝓也應(yīng)該能將它的身體形成一個(gè)、二個(gè)、三個(gè)或更多個(gè)的駝峰形隆肉形式。)

But one kind of lowly sea slug actually has the solar power abilities of a plant. Bizarre but true, the sea slug carries out photosynthesis.(但是，一種不起眼的海蛤蝓竟然擁有植物那樣利用太陽(yáng)能的本領(lǐng)。)

I learned years later that it was in fact a type of Nudibranch, or sea slug.(幾年后，我才知道，事實(shí)上，它是一種裸鰓類動(dòng)物，或者說(shuō)它是一種海蛞蝓。)
