anuses

Constantly resurfacing for air would leave them vulnerable to attacks, so the turtles developed a resourceful skill. They breathe through their anuses.

而连续不断的浮出水面换气，会使得他们变得很容易受到攻击，所以这些海龟就进化出一种特别机智的技能，就是它们可以通过肛门进行呼吸。

murky water caused by all sorts of industrial processes is mucking up the turtles' anuses and has left them teetering on the brink of being wiped out of their preferred habitats.

不过不幸的是，各种工业过程中造成的污浊的水正在影响破坏海龟的肛门，并且已经让它们被迫徘徊在搬离生存已久的栖息地的边缘了。

All of the patients' anuses can control well sparse excrement, fluid and gas. Anorectal pressure had little difference compared to the pressure before surgery.

患者肛门对干稀便、肠液、肠气的控制均正常，愈合后肛管直肠压力与术前相比差别不大。

Despite having round anuses like all other mammals, bare-nosed wombats2 do not produce round pellets, tubular coils or messy piles; they are the only creature on Earth that poops cubes.

尽管和其他所有哺乳动物一样长着圆圆的肛门，但是毛鼻袋熊拉的便便却不是圆球状、螺旋状或乱糟糟的一堆，它们是地球上唯一拉方形便便的生物。

Seriously. Unlike the single-function anuses of other creatures, a turtle's end tube is called a cloaca and deals with the evacuation of all waste.

说真的，不像其他物种的肛门只有唯一的功能一样，海龟尾部的那根管子叫做泄殖腔，就是用来处理各种排泄物的。
