一、世界上最大的蜘蛛 巨蜘蛛比人脸还大(巨毒蜘蛛)

蜘蛛是人们在生活当中经常见到的，但是人们见到的蜘蛛一般都是那种很小的很普通的蜘蛛，肯定是没有见过巨蜘蛛的。因为这种蜘蛛是世界上最大的蜘蛛，也是世界上最大的动物中的一种，你见到了肯定会觉得十分的惊讶，这种蜘蛛甚至比人脸还大!它依靠毒液来腐蚀食物然后吞食，有时候也用爪子将猎物撕碎。

一、世界上最大的蜘蛛

所谓的巨蜘蛛，听到这个名字就应该能感觉它和普通蜘蛛在大小上面有差距的，据相关资料显示，是目前已知的全球最大的蜘蛛，没有之一。它的体型可以超过普通蜘蛛的上百倍甚至是上千倍，是丛林食物链中最顶端的存在。

它的体型能够达到普通蜘蛛的成百上千倍。关于它大小的描述可谓是是少之又少，据科研人员称这种蜘蛛，大小有起码有成年男性的一个拳头大，体重达到了170克，说其可能还是幼崽形态下，不敢相信长大之后会是多么恐怖的一类蜘蛛。据说成年后能够长到人脸那么大，实在是令人可怕。

并且非常的凶猛。它嘴上长着一对尖尖的钩子，袭击时用钩子刺向猎物，同时注入毒液杀死猎物。不幸的猎物在毒液的作用下逐渐变为液体，然后就会被它吸食掉。巨蜘蛛的另一种武器是背上的毒毛。当它受到袭击时，它背上的毒毛会立起来，并将前爪高高扬起对着敌人。

最近有网友上传了一张它的图片，一发布到网络上就立马引起了网友的热议，不少吃瓜群众留言，“这才是真正的蜘蛛精啊!!!”更有人接着回应，“难道这是从盘丝洞走出的白晶晶?!”就是上面这张，在布里斯班山谷里一个动物救援农场里拍到的,型的猎人蛛正在扫帚上爬行!实在是太可怕了。其实除了这种蜘蛛以外，还有着人面蜘蛛，看了让人也是毛骨悚然呐!↓↓↓ 上一页 0 /2 下一页

二、世界蜘蛛最大的是哪个国家

亚马逊巨人食鸟蛛最大了应该！！分布在南美洲北部的雨林

新手怕养不好，没舍得买，网上的图片

自己养了些比较好养的，根本不能比啊

A river-spanning spider web dwarfs a park ranger in Madagascar in 2008. Made of the world's strongest known biological material, the web is the product of a new species, the Darwin's bark spider, which makes the world's largest webs of any single spider, new studies say.

2008年，在马达加斯加岛，一名护林员正在查看一个河流两岸的蜘蛛网。最新研究表明，这个蜘蛛网是用世界上已知的最结实的生物材料编织而成的，它是达尔文吠蛛这一新的蜘蛛种类的产物。这使其成为了当今世界最大的蜘蛛网。

Zoologist Ingi Agnarsson and colleagues have found Darwin's bark spider webs as wide as 82 feet (25 meters)―about as long as two city buses.

波多黎各大学的动物学家Ingi Agnarsson和其同事发现了由达尔文吠蛛结出的宽达82英尺（约合25米）的蜘蛛网，这相当于两辆城市大巴的长度

In Andasibe-Mantadia National Park (pictured), the park rangers knew about them, and I think they've shown them to tourists for a while, said Agnarsson, of the University of Puerto Rico.

Agnarsson说，在Andasibe-Mantadia国家公园（图中所示），“护林员已经知道了这种蜘蛛网的存在，我想他们曾经向游客展示过这些蜘蛛网。”

But the Darwin's bark spider and its record-breaking webs were unknown to science until they were documented by the team, whose findings appear this week in the Journal of Arachnology and PLoS ONE.

但是，在Agnarsson团队发现这些蜘蛛以前科学家对达尔文吠蛛及其破纪录的蛛网一无所知，他们的这一发现将会刊登在这周的《节肢动物学期刊》和《PLoS ONE》杂志上。

达尔文吠蛛的蜘蛛网An approximately three-foot-wide (meter-wide) Darwin's bark spider web hangs above a river in Madagascar.

这张达尔文吠蛛织成的蛛网大约三尺宽（约一米宽），横跨在马达加斯加岛的一条河上。

Though the new species' webs are overall the world's largest, other spiders might exist that create larger orbs―the spiral at the center of the web―according to study co-author Todd Blackledge, a biologist at the University of Akron in Ohio.根据参与这项研究的俄亥俄州Akron大学的生物学家Todd Blackledge介绍，尽管这种达尔文吠蛛织出的蜘蛛网是世界上最大的，但是也有可能存在其他蛛种能够织出更大的圆形蛛网――中心为螺旋结构。 Despite spinning webs of Spider-Man-like size and strength, the Darwin's bark spider uses them to feed mainly on small fry―insects such as mayflies and dragonflies, the team found.研究小组发现，尽管这些蛛网有在强度和尺寸点像蜘蛛侠织出的蛛网，但是这些达尔文吠蛛只是用他们来捕食像蜉蝣和蜻蜓这样的小型飞行昆虫。 In our dreams, we were hoping for bats or birds or something, the University of Puerto Rico's Agnarsson joked.

Agnarsson开玩笑地说道，“按照我们的想象，我们希望这些蛛网能够捕捉蝙蝠或是鸟类这种大东西。”

雌性达尔文吠蛛

The weavers of the largest Darwin's bark spider webs are almost always female, such as this spider pictured in 2008, said Agnarsson, a grantee of the National Geographic Society's Committee for Research and Exploration. 美国国家地理学会研究与探索委员会成员Agnarsson说，最大的蜘蛛网几乎都是由雌性达尔文吠蛛织出来的。上面这张就是拍摄在2008年的达尔文雌性吠蛛的照片。 Juvenile males also weave spider webs, but once they become adults, they abandon this behavior and instead direct their energies solely to sex.幼年的雄性达尔文吠蛛也会织网，不过一旦他们成年后，他们就会放弃这种行为，将全部精力放在和雌性吠蛛交配上。 For survival, the Darwin's bark spider relies in part on its mottled, jagged appearance, which camouflages the spider against trees and―along with Charles Darwin―inspired its name. The species is known to exist only on the island of Madagascar, off Africa's southeastern coast.

为了生存，达尔文吠蛛依靠其色彩斑斓、粗糙的外表与树完美的融为一体，这充分验证查理斯.罗伯特.达尔文的进化论，达尔文吠蛛也因此得名。已知的达尔文吠蛛仅存在于非洲东南岸的马达加斯加岛。

大网捕获小飞虫

Dozens of mayflies hang helpless in a Darwin's bark spider's web in 2008.2008年拍摄的这张图片可以看出，大量的蜉蝣撞上了达尔文吠蛛的蛛网上，变成了达尔文吠蛛的美食。 Darwin's bark spider webs are made out of two basic kinds of silk, Agnarsson explained.Agnarsson解释说，达尔文吠蛛的蛛网由两种蛛丝组成。 Dragline silk is used to create the supporting strands that anchor the endpoints of an orb web to tree branches overhanging rivers or lakes and forms the radial threads in the web. Stretchier, stickier silk is used to create the spiral that captures prey.

“牵引”蛛丝作为支撑股，用来将圆网的一个个终点固定在外悬在河湖之上的树杈上，形成一种辐射状。更具延展性，粘性的蛛丝则被用于织出捕获猎物的螺旋形结构。

When an insect flies into the web, it becomes stuck, and its struggles causes the silk lines to vibrate, alerting the Darwin's bark spider.当昆虫撞到蛛网上时，就会被黏住，其挣扎引起的蛛丝震动，会提醒达尔文吠蛛有猎物上钩了。 The spider then crawls to the captured insect, and envelops it in a silk cocoon to eat at its leisure.然后，蜘蛛会爬向被捕获的猎物，用蛛丝将其包裹起来，闲暇之时慢慢享用。 Unlike most spiders, Darwin's bark spiders will sometimes wrap several insect corpses into a single cocoon, creating a snack pack for later consumption.

不同于大部分的蜘蛛，达尔文吠蛛有时会将多个昆虫尸体过程茧，等到以后享用这一美味。

杰出的成就

Unlike their webs, Darwin's bark spiders aren't very big: Not counting its legs, an adult is usually less than 0.8 inch (2 centimeters) long, Agnarsson said.Earlier this year, study team member Matjaž Kuntner, of the Slovenian Academy of Sciences and Arts, uses a tape measure to determine how high up the center of a Darwin's bark spider web is.今年年初，参与此次研究团队成员，斯洛文尼亚科学与艺术学院的Matjaž Kuntner使用卷尺测量达尔文吠蛛蛛网的中心有多高。

Agnarsson说，与其结出的巨大蛛网不同，达尔文吠蛛并不是非常大：不算腿部，一只成年达尔文吠蛛的长度通常不到0.8英寸（约两厘米）。

An analysis of the Darwin's bark spider's silk indicates it's the toughest biological material discovered to date.对达尔文吠蛛的蛛丝分析表明，它是目前为止最结实的生物材料。 'Tough' means the ability to absorb energy before breaking, and results from a combination of strength and elasticity, Agnarsson explained.Agnarsson解释道，结实意味着它可以在断裂前吸收能量，是强度和韧性完美结合的产物。 The Darwin’s bark spider's silk is about the strength of steel but much, much tougher, because it also stretches. It's many times tougher than even Kevlar, which is one of the best man-made materials.达尔文吠蛛的蛛丝和钢筋的强度差不多，但却比钢筋个结实，因为它具备很强大的延展性。它甚至比最结实的人造材料凯夫拉尔纤维还要结实好几倍。

Behind the Web

蛛网背后的故事

Scientists in 2010 observe the web of an unnamed species that may be a close relative of the Darwin's bark spider and also happens to live in Madagascar's Andasibe-Mantadia National Park.2010年，科学家观察一个尚未命名的蜘蛛种类织网，它可能是达尔文吠蛛的近亲，它们都生活在马达加斯加岛的Andasibe-Mantadia国家公园里。 The central orb structure of this spider's web is about three feet (one meter) wide. By contrast, the orb of a Darwin's bark spider web can be up to nine feet (three meters) across, though most are much smaller.这个蛛网的中心圆形结构宽度大约3尺（约一米）。相比之下，达尔文吠蛛蛛网的中心圆形结构的宽度最多为9英寸（约三米），不过，达尔文吠蛛蛛网多数要比这个小得多。

达尔文吠蛛的陷阱

One of the first things Agnarsson's team wondered after learning about the Darwin's bark spider was exactly how it creates webs wide enough to span bodies of water, such as this river in Madagascar's Andasibe National Park, pictured in 2010.在了解了达尔文吠蛛之后，Agnarsson研究小组首先想要了解的事情是这些蜘蛛是如何织出能够横跨如马达加斯加岛 Andasibe National 公园河宽的蛛网。上面照片摄于2010年。 One of the rangers said the spiders do a Tarzan swing, like they hang down on the silk and swing over, Agnarsson said. We really, really tried to verify that, but it turned out to be false.Agnarsson告诉我们，他说这里的护林员曾说过，达尔文吠蛛可以挂在蜘蛛网上像人猿泰山一样来回游荡。“我们真的试图验证这种说法，而结果证明那根本不可能。” Since then, team member Matjaz Gregorič has discovered the spider's trick and will describe it in a future science paper.此后，小组成员 Matjaz Gregorič 发现了这些蜘蛛的把戏，这将会科学杂志上进行描述。

像不像靶心

Agnarsson, shown behind a Darwin's bark spider web in 2010, hopes that studies of the species will help shed light on mysteries of spider silk.这张照片摄于2010年，Agnarsson站在达尔文吠蛛后面，他希望通过对达尔文吠蛛的研究能帮助揭开有关蛛丝的种种谜团。 Almost all of the spider-silk research has focused on one or two spider species, he said, referring to golden orb weavers and spiders of the Agriopegenus. Our interest is in looking much more broadly across the diversity of spiders.他说：“几乎所有针对蛛丝的研究都集中在一种或两种蜘蛛身上，即大木林蛛和金蜘蛛。我们希望对蜘蛛的多样性进行各位广泛的研究。” There's no reason to think that the two exemplar species that most researchers happen to be studying are among those that make the best silk of all the spiders.他还说，没有理由认为大多数研究者研究的两个典型蛛种就是能够织出最好蛛丝的蜘蛛。

据说是狼蛛。没见过，不过我晓得的ZZ里面。一种叫螃蟹蛛的蛛丝很坚韧的。

织的最硬的蜘蛛网的那只蜘蛛织的网最硬！

不准确啊,还有很多蜘蛛没解密

黑暗游侠连龙都可以网下来的网应该是最硬的吧？
