Orange Baboon Tarantula Facts

Orange Baboon Tarantulas are active, diurnal arachnids native to Central and Southern Africa.

They feed primarily on insects and other small invertebrates, have a typically docile temperament, live upwards of several years in captivity, and can reproduce under proper conditions.


In the wild, these tarantulas enjoy a savannah habitat and can be frequently found amongst dense vegetation, among rocky areas where they spin their webs in search of insects, and sometimes even in abandoned termite mounds.

Due to their bright coloring, these tarantulas can be quite hard to miss when they’re out in the wild.

Behaviourally, these tarantulas are quite active and agile.

They’re capable of climbing trees, running quickly across the ground, and can effortlessly jump from one leaf to another with their long legs.


When in the wild, Orange Baboon Tarantulas typically feed on insects, small lizards, and other invertebrates.

These tarantulas are ambush predators, lying in wait for prey to wander upon them. In captivity, you’ll want to provide the same types of meals.


Pterinochilus murinus are generally docile by nature making them an ideal pet species for those with a passion for spiders.

They can be skittish and defensive when threatened, but in general, they are not inclined to bite people.

However, they are often quick to react and can display aggressive behavior when they perceive a threat.

When threatened, an OBT may rear up on its hind legs, display its fangs, and potentially bite or strike.

 It’s important to handle them with extreme caution, if at all, and to provide them with a secure and suitable enclosure to avoid unnecessary stress or aggression.

It’s also vital to be aware that Orange Baboon Tarantulas are not social creatures, meaning they do not live in colonies and prefer to live alone away from other animals.

In addition, they are notoriously curious so there is a risk of an escape.

As such, ensure that your tank is thoroughly sealed with a secure lid and that crevices and cracks are filled in.


Pterinochilus murinus has a typical tarantula lifespan of many years with proper care. Females usually live longer than males with an average of up to 15 years, while males live up to 4 years.

When young, they can grow relatively quickly, with molting usually happening every 4-8 weeks in the first 2 years.

By their 3rd year, the molting schedule slows to every 6-10 months as they reach full size. 

The life cycle of an Orange Baboon Tarantula goes through several stages – spiderling, subadult, and adult.

As they age, the molts act as mini-renewals as the tarantula can shed its old exoskeleton and grow into a bigger and stronger specimen. 


Mating and reproduction amongst Orange Baboon Tarantulas is a fascinating process.

Once maturity is reached, males will create a sperm web which they will use to deposit sperm, and then the female will join them for mating.

After mating, the female will lay a clutch of one to three egg sacs which may contain hundreds of eggs.

The eggs usually hatch in two to four weeks, and the tiny, delicate spiderlings will remain under the mother’s care until they are independent enough to survive on their own.

Where To Find Orange Baboon Tarantulas

In the wild, Pterinochilus murinus can be found mainly in East Africa and a few other parts of the continent.

This species prefers dry, arid forests and grasslands, meaning they’re often difficult to find in the dense jungles of Central and West Africa. 

Finding captive-bred Orange Baboon Tarantulas for sale is typically easier for most of us.

This species has become quite popular among tarantula keepers due to its hardy nature and striking coloration.

It’s recommended to buy from trusted breeders or pet stores, as wild-caught specimens can be difficult to care for and are often infected with parasites. 

Furthermore, it’s also good to make sure the tarantula you’re purchasing is not an adult.

Buying a younger, sub-adult specimen will ensure you can see the tarantula reach its full potential as an adult.

Orange Baboon Tarantula Care

To provide optimal care for Pterinochilus murinus, it is vital to consider their natural habitat and behavior, the type of enclosure, temperature, furnishings, and decor needed.

Also have a good understanding of selecting the recommended prey items, how often to feed them, how to handle them safely, basic health and hygiene, and potential health issues to watch out for.

Tank Requirements

The ideal tank requirements for an Orange Baboon Tarantula depend on its natural habitat.

This species is native to African rainforest areas and prefers high humidity levels with a temperature ranging from 75 to 80 degrees Fahrenheit.

A terrarium of at least 10-15 gallons is recommended and the terrarium substrate should be composed of 3-4 inches of coco fiber and peat moss.

Enclosures with a waterproof seal and locking lid are best, along with good air circulation and a water dish for providing humidity.

The terrarium lighting should be dim as this species is nocturnal and the pH levels should be between 6.5 and 7.5 with a water hardness between 3 and 10 dKH.

What Do Orange Baboon Tarantulas Eat?

Feeding an Orange Baboon Tarantula is a relatively simple task.

They are primarily insectivores that feed and prefer a variety of live prey items such as cockroaches, locusts, crickets, earthworms, snails, and slugs.

It’s essential to feed the tarantula prey items that are no larger than the width of its body.

Ideally, you should feed them once every 1-2 weeks, as this will provide them with the required amount of sustenance. 

It is also important to ensure that the prey you feed the tarantula is fresh and not rotten.

If you are not able to acquire live prey, you can also use dried and commercial diets; however, fresh prey is recommended.

Additionally, always ensure that any prey you feed your arachnid is properly gut-loaded with nutritious, known-healthy foods and supplemented with vitamins and minerals.
