The Socotra Island blue baboon tarantula is a large, vivid blue spider that lives on the ground. It is found only on Socotra Island, which is part of Yemen, and it is known for its unusual group behaviour, where mother spiders guard their young. Its venom has not been studied enough to know how strong it is.1

The abdomen is cream or grey and partly blue.1
Rare red and amber variants have been seen.1

毒液力量

咬

咬的時候，毒液會從毒牙或牙齒出來。

牠的毒液有什麼作用？

The potency of its venom is not known. Some people believe it can kill a dromedary (a one-humped camel), but this is most likely not the case.1

牠對人有多危險？

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

How strong its venom is has not been established. When provoked, especially when a mother is protecting an egg sac, it will deliver a fast strike and bite.1

牠害怕時會做什麼？

When threatened, it rears up on its hind legs and bares its chelicerae (fang-bearing mouthparts) in a characteristic threat pose. Further provocation leads to a fast strike and bite.1

如果牠咬人

清洗咬傷處並冷敷。如果很痛或傷者覺得不舒服，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

值得知道

小知識

Its vivid blue colour is the striking feature of the adult, although red and amber forms have been seen very rarely.1

This tarantula is communal: mother spiders care for their young and will attack predators that get too close to their egg sac.1

In captivity, several males and females of different ages can live together without attacking one another, as long as they have enough food and proper care.1

Females live for about 10 to 14 years, while males tend to live for only about 3 to 4 years.1

Because it is an Old World tarantula, it does not have urticating hairs, the irritating hairs that some New World tarantulas flick at attackers.1

破解迷思

迷思： It can kill a dromedary (one-humped camel).

真相： Some people believe this, but it is most likely not the case. Its venom potency is not known.1
