The Moon is between the Earth and the Sun, so from our perspective we only see the dark half, the unilluminated half, of the Moon.

月亮正处于地球和太阳之间，所以从我们的角度上只能看见月亮的暗面，即不被照亮的一面。

In particular, several threatened species, including Munk's devil ray (pictured) and the diamond stingray, turned up less often in the illuminated than the unilluminated nets.

特别值得一提的是一些濒危物种，包括芒克魔鬼鱼和钻石黄貂鱼，在有照明的渔网中出现的频率低于没有照明的渔网。
