【TED-Ed】能排出糖果便便的虫子 |The bug that poops candy
发布人
Aphids can reproduce incredibly fast: they can make 20 new generations within a single season. And that means lots of poop. Some aphid populations can produce hundreds of kilograms of poop per acre— making them some of the most prolific poopers on the planet. We know this poop as the sweet, syrupy liquid called honeydew. George Zaidan explores the wonderfully weird life of an aphid. 蚜虫繁殖后代的速度令人难以置信:一个季节它们能繁殖 20 个世代。这也意味着会产生大量的粪便。一些蚜虫种群可以在每英亩地产生几百公斤的粪便——这使得它们成为了这个星球上排泄能力最强的生物之一。我们把这种甜甜的、糖浆状的粪便叫做蜜露。乔治·扎丹(George Zaidan)探索了蚜虫神奇的一生。
