Trichonephila clavipes. Trichonephila clavipes (formerly known as Nephila clavipes), commonly known as the golden silk orb-weaver, golden silk spider, golden orb weaver spider or colloquially banana spider (a name shared with several others), is an orb-weaving spider species which inhabits forests and wooded areas ranging from the southern US ...
Phoneutria nigriventer is a large spider. Its maximum body length is around 5cm and its legs can span 15cm in larger individuals. Its body is covered in thick brown hair. [4] They are nocturnal, and actively hunt at night, killing by ambush rather than using a web; during the day, they are found hidden under logs or crevices.
The spiders in the genus can grow to have a leg span of 13 to 18 cm (5 to 7 in). Their body length ranges from 17 to 48 mm (43 ⁄ 64 to 1 + 57 ⁄ 64 in). [4] [5] While some other araneomorph spiders have a longer leg span, the largest Phoneutria species have the longest body and the greatest body weight in this group. [6]
It is the banana spider’s doppelganger, the Brazilian Wandering Spider, that was named the most venomous animal in 2007 by the Guinness Book of World Records. To tell the two apart, take a ...
The pathophysiology of a spider bite is due to the effect of its venom. A spider envenomation occurs whenever a spider injects venom into the skin. Not all spider bites inject venom – a dry bite, and the amount of venom injected can vary based on the type of spider and the circumstances of the encounter. The mechanical injury from a spider ...

Argiope appensa construct webs mainly in bushes, between branches, and in human constructions. The webs are rather large and show a white zig-zag silk decoration developed from one corner to the center of the web. [3] These decorations, usually called stabilimenta, could be a warning device to prevent birds from inadvertently destroying the web.
Nephila spiders vary from reddish to greenish yellow in color with distinctive whiteness on the cephalothorax and the beginning of the abdomen. Like many species of the superfamily Araneoidea, most of them have striped legs specialized for weaving (where their tips point inward, rather than outward as is the case with many wandering spiders).
