The eastern mouse spider is a spider from the family Actinopodidae. It lives only on the eastern coast of Australia. People often mistake it for the Australian funnel-web spider, which is more dangerous, so knowing the difference matters.1

It lives in burrows in the ground. Males wander around in autumn and early winter looking for mates, and they sometimes fall into swimming pools.1

見分け方

Females are large and very strong, with powerful jaws called chelicerae.1
Females have a shiny black carapace (the hard upper shell of the body) and an abdomen (rear body) coloured brown to almost black.1
Males have an all-black carapace and a trapezium-shaped (four-sided, with two parallel sides) lighter patch on top of the abdomen, which can be white, pale blue or mauve.1
Their fangs often cross over slightly.1
The burrow entrance is hidden by a flap of silk, which can be found by brushing away loose soil.1

よくまちがえられるのは： It is often mistaken for the Australian funnel-web spider. Funnel-web fangs stay parallel, while mouse spider fangs often cross over slightly. Funnel-webs often have a drop of venom on their fang tips and have longer spinnerets (silk-producing organs at the rear of the abdomen).1

毒パワー

かむ

かむときに、毒が牙や歯から出るよ。

その毒（かむ・刺す毒）はどうなるの？

Common symptoms of a bite are numbness and tingling at the bite site, sweating, headache and nausea. Its venom contains toxins similar to robustoxin, the toxin found in Australian funnel-web spider venom. Severe reactions are rare.1

人にとってどれくらい危険？

人への危険: 深刻かまれたらお医者さんへ。死ぬことはとてもまれだよ。

Although it appears to be the most dangerous member of its genus, serious envenomations by this species are relatively rare. Most documented bites did not need antivenom or cause serious symptoms. Only one severe case is recorded: a 19-month-old child who developed high blood pressure, muscle spasms, an arched back and unconsciousness.1

こわいとき、どうするの？

Compared with the Australian funnel-web spider, it is far less aggressive towards humans and often gives dry bites, which deliver no venom.1

かまれたら

The child with the severe case responded well to funnel-web spider antivenom. Australian funnel-web spider antivenom has been found to be effective in treating severe mouse spider bites.1
かまれたところを洗って冷やそう。痛みが強かったり、その人の具合が悪くなったりしたら、医療の助けを受けて。
オーストラリアでは、大きな黒いクモにかまれたら、ジョウゴグモにかまれたものとして手当てしよう：圧迫固定法：かまれたところの上から、しっかりした伸びる包帯をまき、そのまま手足全体にまき上げ、添え木で固定して、助けが来るまでその人をまったく動かさないようにしよう。
