Fringed jumping spider

Portia fimbriata

無害對人無害。不用擔心。

咬吃：肉

The fringed jumping spider is a small jumping spider from Australia and Southeast Asia. It is a skilled hunter that often catches other spiders, including web-building spiders. Its slow, jerky walk helps it creep up on prey without being noticed.1

在陸地上, 粗略估計

牠吃什麼？

Hunts other jumping spiders, web-building spiders and insects, and also eats spider eggs. It stalks prey slowly, or plucks a web to lure out or calm the prey before biting it. Females also catch prey in their own webs.1

Females have two white stripes forming an M on the front body. Males have a white strip around the lower edge of the back half and a white groove down the back.1

毒液力量

咬

咬的時候，毒液會從毒牙或牙齒出來。

牠對人有多危險？

對人的危險: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

牠害怕時會做什麼？

When disturbed, it often holds a cryptic rest posture, pulling its legs and palps close to hide their outline, and most Portia species leap upwards 100 to 150 mm.1

如果牠咬人

清洗咬傷處，用冰敷袋冰敷止痛。如果很痛、疼痛擴散或傷者覺得不舒服，要就醫。

一定要先打緊急電話（112、000、911）。這是一般急救指引，不是醫療建議。急救基本知識

注意安全

絕對不要碰、抓或捉弄野生動物，就算是很小的動物，就算牠看起來在睡覺或已經死了也一樣。
給牠空間。如果遇到了，保持冷靜，慢慢往後退，讓牠自己離開。
如果被牠咬了：保持冷靜，保持不動，打緊急電話（112、000、911）或趕快去醫院。記住牠的樣子，有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己，而且牠更想躲起來。更多安全知識

牠有多快？

小知識

It can hunt inside another spider's web. Its slow, choppy movements and leg flaps make it look like leaf debris blown in the breeze.1

Its main eyes are very sharp. It can tell prey and other spiders apart from up to 280 mm away, about 47 times its own body length.1

In Queensland, it uses a 'cryptic stalking' technique that stops most jumping spider prey from recognising it as a predator, or even as an animal.1

Its hunting is so flexible that it is sometimes called an 'eight-legged cat', after the adaptable hunting of a lion.1

Unlike other Portia species, females do not eat their mates during courtship or after mating.1
