Redback spider
The redback spider is a highly venomous spider. It is thought to come from Australia, but it now also lives in Southeast Asia, Japan and New Zealand. It often lives close to people, in warm, sheltered places in and around homes, so it matters a great deal for safety.1

Paano ito makikilala
- The adult female has a round, shiny black body with a red stripe on the top of the abdomen.1
- Underneath, she has an hourglass-shaped red or orange streak.1
- The female's body is about 1 cm long, with slender legs.1
- The male is much smaller, 3 to 4 mm long, light brown with white markings on the upper abdomen and a pale hourglass marking underneath.1
- Its web is an irregular, untidy tangle of strong silk, usually in a warm, sheltered spot.1
Madalas mapagkamalang: The false redback spider (Steatoda capensis) has a similar build but is uniformly black or plum-coloured, and it has no red stripe on its abdomen.1
Lakas ng kamandag
Lumalabas ang kamandag sa pangil o ngipin nito kapag nangangagat ito.
Ano ang epekto ng kamandag nito?
The venom is neurotoxic to vertebrates, meaning it attacks the nerves, and it causes a condition called latrodectism. Pain starts around the bite and typically becomes severe, spreading up the bitten limb and lasting for over 24 hours. Localised sweating in patches of skin is highly indicative of latrodectism, and nausea, vomiting, headache and agitation may indicate severe envenomation.1
Gaano ito kapanganib sa tao?
Panganib sa tao: MalalaKailangang magpatingin sa doktor kapag nakagat. Napakabihira ng namamatay.The redback is one of the few spider species that can seriously harm humans. Because it often lives in buildings, it is responsible for a large number of serious spider bites in Australia.1
Magandang balita: may gamot (antivenom) o gamutan ang mga doktor para dito.1
Ano ang ginagawa nito kapag natatakot?
Its bright scarlet markings may serve as a warning to potential predators.1

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
A male redback can successfully mate with a female katipō, a related New Zealand spider, producing hybrid offspring.1
Males often mate with a female who may then eat them, a behaviour called sexual cannibalism that many arachnids show while mating.1
In laboratory tests, redbacks survived an average of 100 days, and sometimes over 300 days, without food.1
After mating, a female can store sperm for up to two years and use it to fertilise several clutches of eggs.1
Spiderlings and larger females steal food from other spiders' webs, and spiderlings sometimes eat their less active siblings.1
