Orange Baboon Tarantula-Pterinochilus Murinus

Orange Baboon Tarantula-Pterinochilus Murinus

As depicted from the name the orange baboon tarantula ordinarily alluded as the orange bitey thing(Pterinochilus Murinus) is one of the largest spiders in the world which generally dwells in the vast continent of Africa.

It is observed that due to their quite remarkable adaptability to different climate changes, the species have managed to make a habitat in Angola, as well as central, eastern, and southern Africa.

Are OBT Tarantulas Poisonous?

These exotic species with bright yellow colour and a golden brown shine appear versatile but are very lethal as they are venomous and it is quite rare for a hospital to have an antivenom for a spider bite.

So, if you got one of those then they can be pretty nasty at times. If bitten you may experience swelling, intense burning sensations and cramps for a week or so.

We couldn’t find the type of venom they have but apart from that it is well known that orange baboon tarantula bites are very painful.

It is often said that their bite is more painful than a rattlesnake’s bite.

Of course one shouldn’t test this. The bite from the orange baboon tarantula (Pterinochilus Murinus)is not lethal but a rattlesnake will probably kill you.

OBT can bite and ingest venom multiple times depending upon the conditions.

It is seen that the venom takes some time to act(20-30min).

The bitten area often swells up and there is an intense burning sensation.

This might last for some time following with cramps. The body might try to fight it off which may cause a slight fever.

If you find yourself in this unfortunate position wash the influenced area with water and soap, apply a cool compress, apply an ointment, take some antibiotics and a painkiller if needed.

If in a rare case you have an allergic reaction or some life-threatening symptoms like difficulty in breathing or chest pain consult a doctor immediately.

In recent years the reptile-loving community has grown and the number of collectors and enthusiasts has also grown and with some unique traits shown by this spider they are always under spotlight among other tarantulas.

It is also known as the Mombasa golden starburst tarantula(Pterinochilus Murinus).

The particular trait which is applauded the most is their remarkable striking pose or generally termed as the threat display.

When threatened or provoked in any manner they will surely bite.

The threat display(demonstration of the fangs) are clearly visible with the blucolourolor present at the end of its legs highlighting the frightening experience.

Just the thought about a large venomous spider leaping towards you is enough to send shivers down anyone’s spine. Due to their aggressive nature, it is often advised to only handle the orange baboon tarantula, if having prior experience with other venomous spiders.

Identification-(Pterinochilus Murinus)

They are identified mainly by thcolourolor which is bright orange and it can vary slightly according to the geographical location.  

Size of orange baboon tarantula-

Being in the tarantula family these spiders are pretty large but when compared to some other of the same species like goliath bird eater tarantula which can be of 10-11’’ long they pale in comparison.

On the other hand, the biggest the orange baboon tarantula gets is 6’’.

As the trait goes with other spiders same for them the females are bigger in size than the males. The females can be of 4-6’’ while the males ranging from 3-4’’.


The males mature in a year or so but do not live long after. Depending upon how they are raised and taken care of you can prolong their life to 2 years max.

The females, however, get to live a longer life of 8-10 years which is three to four times the lifespan of a male.

Captive environment-

The basic necessities should be fulfilled like fresh water at all times, food at specific intervals. It is advisable to create an ecosystem where they feel like home. The humidity of the container should be well preserved.

Of course, the nation ate insects and remains should be removed regularly.

Dead bodies lying around never do any good. The tank or cage in which the spider is kept is often transparent so made of either glass or hard plastic or fiber.

It is very important to keep the tank well ventilated which is generally accomplished by having many small holes. In the wild, the orange baboon tarantulas make home in burrows.

They are often seen inside hollow trees. The amount of web the orange baboon spider makes is astonishing.

So, it is advisable to not buy a very fancy cage as it will soon be covered in webs.

They might make a burrow in the cage that you have provided them with or just hide along the other components of the cage.


Their diet in the wild include insects like crickets, moths, grasshoppers, etc. they also feed upon small birds, lizards or even snakes. Being carnivores they pretty much feed upon any prey that they can kill. 

Do Orange Baboon Tarantulas(Pterinochilus Murinus)make good pets-

No, they do not. THEY ARE SPIDERS. They are a beautiful looking species but only from a distance.

Spiders are not able to process emotions or even feel any kind of emotional connection.

It does not matter if you have been taking care of them for five years, if you provoke them in any manner they will still bite you.

They have good hunting instincts which help them survive. So, it would be wise to not treat them as normal pets and please never try to pet them.


The males can mature in a year and the females take six months more or so. After they have molted you have to wait for a few weeks before mating.

The females are undoubtedly bigger than the males so, after mating it would be wise to keep them in different containers because the female might be interested in eating the male.

It is necessary to understand that they make a cocoon probably 2-6 months after mating and a second cocoon is made after about 8 months. About 75-150 baby spiders are expected from one cocoon.
