先贴The tarantula scientist里的一段关于tarantula’s hair的作用:
For most tarantulas, biting is a defense they’d rather not use at all. They’d rather hide. If that doesn’t work, some tarantulas use a defense more effective than fangs or venom: their hairs!
How can tarantulas use hair to protect themselves? Sam(书中的科学家) explains: When irritated, most New World tarantulas(those from North and South America) will use their rear pair of legs to kick hairs off their back end. Each hair is covered with tiny barbs like a porcupine(豪猪,箭猪) quill but is light enough to float on air currents.
Sam has had a few “hairy” experiences himself. He knows firsthand that these barbed hairs can get into the folds of skin in your neck, between your fingers, into your eyes, up your nose. The result? Itching and sneezing that make a smart predator leave the tarantula alone.
总的来说通俗易懂吧,孩子听了兴趣盎然,每天乐乐都会央求我再读一段,怪不得是获奖书呢!
