Darwin's bark spider
Darwin's bark spider is an orb-weaver that builds the largest orb webs ever seen. It lives in the forests of Madagascar, where it hangs its web over rivers and lakes. Scientists found it in 2009, and it has unusually tough silk.1

Paano ito makikilala
- Females are largely black, with white hairs on the body and legs.1
- The top of the front body section has two pairs of raised humps, one at the sides and one towards the back.1
- Females are about 1.8 to 2.2 cm long, while males are around 0.6 cm.1
- Males are redder and lighter brown, with white hairs and red, hairless leg segments (femora).1
- Webs are very large, up to 2.8 square metres, and are strung over water.1
Madalas mapagkamalang: Other Caerostris species live in the same region of Madagascar. Darwin's bark spider has clearly separated epigynal chambers (parts of the female's genital plate) with a pair of hooks at the back, which the other species from the region do not have.1
Lakas ng kamandag
Lumalabas ang kamandag sa pangil o ngipin nito kapag nangangagat ito.
Gaano ito kapanganib sa tao?

Kung kumagat ito
- Hugasan ang kagat at lagyan ng ice pack para sa sakit. Kumuha ng tulong medikal kung matindi ang sakit, kumakalat, o masama ang pakiramdam ng tao.
Laging tawagan muna ang numero pang-emergency (112, 000, 911). Ito ay pangkalahatang gabay sa pangunang lunas, hindi payong medikal. Mga batayan ng pangunang lunas
Mag-ingat
- Huwag kailanman hawakan, hulihin o asarin ang ligaw na hayop, kahit maliit, at kahit mukha itong tulog o patay.
- Bigyan ito ng espasyo. Kung makasalubong ka ng isa, manatiling kalmado, dahan-dahang umatras at hayaan itong umalis.
- Kung kagatin ka ng isa: manatiling kalmado, huwag gumalaw, tawagan ang numero pang-emergency (112, 000, 911) o pumunta agad sa ospital. Tandaan ang itsura nito, makakatulong ang litrato.
Hindi ka nito hinahabol. Ginagamit nito ang kamandag para manghuli ng pagkain o ipagtanggol ang sarili, at mas gusto pa nitong magtago. Higit pa tungkol sa pag-iingat

Mga fact
Its silk is the toughest biological material ever studied. It is over ten times tougher than a similar amount of Kevlar.1
Its web is the largest orb web ever observed, covering up to 2.8 square metres. Its bridge lines can span up to 25 metres.1
The spider uses a set of web-building behaviours that are unknown in other spiders. It releases bridge silk into the air so the wind carries it across the water.1
Females are much larger than males, sometimes many times heavier. This is one of the most extreme size differences between the sexes in spiders.1
Flies that feed on its catches have been found living alongside it, and the spider sometimes chases them away.1
