世界上最巨型既蜘蛛是Goliath Birdeater. 係毛蜘蛛ge一種. 通常會食蜥蝪等一類無脊椎動物. 應該仲未發現好似"近蛛者殺"果套戲入面d spider咁大, 個套戲好似係講spider d 基因特變先搞到佢地咁大隻咋ma. 不過基因工程繼續發展再加上環境繼續被破壞, 可能li d巨蜘蛛都唔係無可能出現.

The Goliath Bird Eating Spider (also called the Birdeater) (Theraphosa blondi) is an arachnid which belongs to the tarantula family, and is arguably the largest spider in the world. The spider was named by explorers from the Victorian era, who witnessed one eating a hummingbird and reported the sighting to the Western world.[1]

Native to the rain forest regions of northern South America, these spiders have up to a 30 centimetre (12 in) long leg span when fully extended and can weigh over 120 grams. Wild Goliath birdeaters are a deep burrowing species, found commonly in marshy or swampy areas. Goliath bird eaters usually live in burrows in the ground that they have either dug themselves or have been previously abandoned by rodents or other similar creatures.

Female birdeaters mature in 2.5-3 years and have an average life span of 6 to 14 years. Males die soon after maturity and have a lifespan of 3 to 6 years. Colours range from dark to light brown with faint markings on the legs. Birdeaters have hair on their bodies, abdomens, and legs. The female lays anywhere from 100 to 400 eggs, which hatch into spiderlings within two months.

Male birdeaters are one of the few tarantula species to lack tibial spurs, located on the first pair of legs of most adult male tarantula species. These spurs are used by other tarantulas to keep the fangs of the female immobilized during mating so the female doesn't eat the male.

The Goliath birdeater is fairly harmless to humans, as are most species of tarantulas. Like all tarantulas, it has fangs large enough to break the skin of a human (1-2.5 cm). They do carry venom in their fangs and have been known to bite humans when threatened, but the venom is relatively harmless and just causes swelling and mild pain for a few hours (like a wasp sting). Tarantula bites to humans are usually in self-defense and do not always contain spider venom - what is known as a "dry bite". The goliath spider also does not have very good eyesight and mainly relies on vibrations in the ground that they can sense from their burrows in the ground.

Birdeaters are defensive and may make a hissing noise when disturbed. This noise is called stridulation, and is produced when the spider rubs the bristles on its legs together. Birdeaters can defend themselves by biting or by kicking urticating hair towards their perceived assailant. These hairs can be severely irritating to the skin and lungs, and have been reported to feel like shards of fiberglass.

Despite its name, the Goliath birdeater does not normally eat birds. Rather, it eats mostly invertebrates such as crickets, mealworms and moths, and also small vertebrates such as frogs, mice, and lizards. The Goliath birdeater is one of the few tarantulas which can capture and eat a full-grown mouse.

世界最大的蜘蛛
蜘蛛的种类很多,全世界已知的蜘蛛种类就有35000种。但是不同种类的蜘蛛个体大小彼此间悬殊很甚,大的很大,小的甚小,而且雄雌个体大小也有差异。世界上最大的蜘蛛是南美的“食鸟”蜘蛛,它西在树林中织网,以网来捕捉自投罗网的鸟类为食。这种“食鸟”蜘蛛据说在上海市郊区曾发现过:一位工人述说,他在钓鱼的时候曾见过两次,有拳头那么大的捕食鸟蜘蛛,因体形奇异惊人,当时不敢轻易用收取碰它。
世界最巨大的蛇
印度尼西亚捕获一条长14.85米,重447公斤的巨蟒。到目前为止,这条蟒蛇是世界上最大的蟒蛇.

这条大蛇是在印尼西部苏门答腊岛的一个原始森林中被发现的,当地人将它捕获后卖给了公园,公园的管理人员将这条大蛇取名为“桂花”。虽然名字听起来比较温柔,但据说“桂花”的大口一旦张开非常吓人,可以很轻松地吞下整整一个人。

  印尼当地媒体报道说,印尼的国家科学研究所、农业研究所等学术机构都对这条蛇进行了检验,确认了其身长、体重以及品种。很多动物学家都表示,从来没有见过这么大、这么长的蛇。

  据说,要制服这么大的蛇,至少需要8到10个壮年男子。此前,吉尼斯世界记录中所记载和公认的世界最长蛇是一条身上花纹呈网状的大蟒,身长10米,已于1912年在印尼被射杀。

  研究所的动物学家还透露说,此次发现的这条世界上最长的蛇是东南亚的“土著蛇”,在印尼、菲律宾等国家都比较常见,但一般都没有这么长。

亚马逊森蚺也是当今世界上最大的蛇,最长可达十公尺,重达二百二十五公斤以上,粗如成年男子的躯干;但一般森蚺长度在五公尺半以下。

  森蚺生性喜水,通常栖息在泥岸或者浅水中,捕食水鸟、龟、水豚、貘等,有时甚至吞吃长达两公尺半的凯门鳄。森蚺会把凯门鳄紧紧缠绕,直到它窒息死亡,然后整条吞下去,以后几个星期,不用进食。

  尽管成年森蚺是极可怕的猎食动物,但是幼蚺出生时,长不过七百六十公厘。幼蚺是胎生的,有时一胎达七十条左右。许多幼蚺被凯门鳄吃掉。幸存的长大后,就反过来吞食凯门鳄~!

  他们被认为是世界最重的蛇。喜欢生活在沼泽、浅溪和静止的河川中,是秦水性最大的巨蛇。森蚺大部份在夜间活动,但也常在大白天看到它在晒太阳。
