\u00d6r\u00fcmcekler g\u00fcn\u00fcm\u00fcz teknolojisinin bile \u00e7\u00f6zemedi\u011fi inan\u0131lmaz canl\u0131lard\u0131r. \u00d6r\u00fcmcek a\u011f\u0131n\u0131n \u00e7ok \u00f6zel nitelikleri olan sa\u011flaml\u0131k ve esneklik bug\u00fcne kadar taklit edilemedi. Ayn\u0131 \u00e7aptaki bir \u00e7elik telden iki kat daha g\u00fc\u00e7l\u00fc olan bu doku ne kadar \u00e7ekilirse \u00e7ekilsin orijinal durumuna d\u00f6necek kadar esnektir.<\/p>\n
\u00d6r\u00fcmcek a\u011flar\u0131 kendine y\u00fcksek h\u0131zla \u00e7arpan nesneleri y\u0131rt\u0131lmadan esneyerek frenler. Tekrar gerisin geriye yaylanmad\u0131\u011f\u0131ndan nesne ters y\u00f6ne f\u0131rlamaz, yap\u0131\u015f\u0131r kal\u0131r. \u00d6r\u00fcmcek a\u011f\u0131n\u0131n esneme kapasitesi bug\u00fcn yapay olarak \u00fcretilmi\u015f en iyi telin neredeyse d\u00f6rt kat\u0131d\u0131r.<\/p>\n
Bu maddeyi yapay olarak elde etmeyi hala ba\u015faramayan bilim insanlar\u0131n\u0131n \u00f6r\u00fcmcek \u00e7iftli\u011fi kurup, \u00f6r\u00fcmcekleri sa\u011farak, ipliklerini ald\u0131klar\u0131n\u0131 biliyor muydunuz? Yakla\u015f\u0131k 2,5 santimetre boyundaki bu \u00f6r\u00fcmceklerden g\u00fcnde hayvan ba\u015f\u0131na 320 metre (yakla\u015f\u0131k 3-5 gram) iplik elde ediliyor ve bu iplikler ABD ordusuna kur\u015fun ge\u00e7irmez yelek yapmada kullan\u0131l\u0131yor.<\/p>\n
D\u00fcnyada 34 bin \u00f6r\u00fcmcek cinsi tespit edilmi\u015ftir. Yani her cins \u00f6r\u00fcmcek farkl\u0131 \u00f6zellikler ta\u015f\u0131r. \u00d6r\u00fcmceklerin hepsinde zehir bezleri vard\u0131r, ama karadul \u00f6r\u00fcmce\u011fi, kahverengi \u00f6r\u00fcmcek gibi \u00e7ok az t\u00fcr\u00fc insana zarar verebilir. D\u00fcnyan\u0131n en b\u00fcy\u00fck \u00f6r\u00fcmce\u011fi ise G\u00fcney Amerika’n\u0131n kuzey k\u0131sm\u0131nda ya\u015fayan ‘Goliath Tran-tula’ isimli dev \u00f6r\u00fcmcektir. Erke\u011finin baca\u011f\u0131n\u0131n boyu 25 santimetreyi bulur. Kurba\u011falan, kertenkeleleri, fareleri ve hatta k\u00fc\u00e7\u00fck y\u0131lanlar\u0131 yakalay\u0131p yiyecek kadar g\u00fc\u00e7l\u00fcd\u00fcr.<\/p>\n
\u00d6r\u00fcmcekler, di\u011fer b\u00f6ceklerden farkl\u0131 olarak sekiz baca\u011fa ve sekiz g\u00f6ze sahiptirler. B\u00fcy\u00fcme safhas\u0131nda bir bacak k\u0131nl\u0131rsa yerine yenisi gelebilir. V\u00fccutlar\u0131 iki par\u00e7a olup arka k\u0131sm\u0131ndaki bezlerden a\u011f \u00fcretimi ba\u015flar, buradaki \u00e7ok ince deliklerden s\u0131v\u0131 ve damlalar halinde verilen a\u011f malzemesi d\u0131\u015far\u0131 \u00e7\u0131kar \u00e7\u0131kmaz donar.<\/p>\n

Kurban a\u011fa yakalan\u0131nca yap\u0131\u015fkan k\u0131sm\u0131 bildiklerinden kendileri de a\u011fa yakalanmadan onun yan\u0131na kadar giderler. \u00d6r\u00fcmcek a\u011f\u0131n\u0131 amac\u0131na g\u00f6re farkl\u0131 \u015fekillerde \u00f6rer. A\u011fdaki ipliklerin de cinsleri yerlerine g\u00f6re farkl\u0131d\u0131r. Yumurtalar\u0131n sarmalanmas\u0131 i\u00e7in \u00fcretti\u011fi yumu\u015fak iplik onu ayn\u0131 zamanda bir u\u00e7urtma gibi u\u00e7urabilir. A\u011f\u0131n ana yap\u0131s\u0131, dairesel k\u0131s\u0131mlar\u0131, av\u0131 yakalayacak k\u0131sm\u0131 i\u00e7in elastikiyetleri ve sa\u011flaml\u0131klar\u0131 farkl\u0131 ipler \u00fcretir.<\/p>\n
\u00d6r\u00fcmceklerin bir\u00e7ok t\u00fcr\u00fcnde erke\u011fine g\u00f6re 4 – 5 kat b\u00fcy\u00fck olan di\u015finin \u00e7iftle\u015ftikten sonra erke\u011fini yedi\u011fi do\u011frudur. Ancak bu erkeklerin bir gecelik zevk u\u011fruna katland\u0131klar\u0131 bir sonu\u00e7 de\u011fil, kendi nesillerini devam ettirebilmek, kendi evlatlar\u0131n\u0131 \u00fcret-tirebilmek i\u00e7in kendilerini di\u015fiye kurban etmeleridir.<\/p>\n","protected":false},"excerpt":{"rendered":"
