mouthparts

基本解釋

Different niches, having different requirements, result in different genes and different shaped mouthparts.
不同的環(huán)境，對(duì)物種有不同要求，從而産生了不同的基因和不同形狀的口器。
But the male spiders have a problem with the basic strategy, for mating rituals demand that they sport elongated mouthparts, which could detract from the overall antlike effect.
但雄蛛在實(shí)行這個(gè)戰(zhàn)略上有一點(diǎn)點(diǎn)小問題，因爲(wèi)在交配儀式上雄性會(huì)被要求炫耀和展示它們細(xì)長(zhǎng)的口器，這會(huì)讓雄蛛表現(xiàn)得不那麼像螞蟻。
