When an ant falls in, the spider simply waits for it to drown
螞蟻掉到陷阱里了，蟹蜘蛛靜靜等它淹死，
and then abseils down for a spot of fishing.
直接坐收漁翁之利。
Alive, this ant would be far too dangerous for the spider to tackle,
要生存，螞蟻必須遠(yuǎn)離蜘蛛的魔爪，
so using the pitchers as traps means it can get bigger meals.
但是利用豬籠草的陷阱意味著蟹蜘蛛照樣可以美餐一頓。
And the spider doesn't rob the pitcher of everything.
蟹蜘蛛也不全是一個不留。
The digested remains of its booty will end up in the water, providing instant food for the plant.
它也需要把戰(zhàn)利品分一部分給豬籠草，來給豬籠草提供營養(yǎng)。
Other food, like mosquito larvae, seems to be out of reach,
有的食物，例如蚊子幼蟲，在瓶底看上去好像吃不到，
but the spider has another surprising trick.
不過蟹蜘蛛自有詭計。
By taking its own air supply trapped in a bubble,
它會帶著一個空氣泡泡，
the crab spider can actually dive to the very bottom of the pitcher.
蟹蜘蛛可以潛入到豬籠草的底部。
Once the prey is captured, the spider hauls itself back up its silken safety line.
一旦獵物到手，蟹蜘蛛還可從水中全身而退。
The pitcher is a one-stop shop for this spider, but it's not alone.
豬籠草好像是蟹蜘蛛的一站式商店，但它并不孤獨。
In the jungle there's competition for everything, even a small water-filled pitcher plant.
雨林中到處都有競爭，即使在豬籠草的小小水域里。
