About
Purcell's Baboon (Harpactira baviana, Purcell 1903 - ignore vendor pages crediting Pocock) - a small, smart South African baboon from semi-arid Karoo scrub, building elaborate tunnel-and-tube web architecture instead of a simple burrow. One of the most manageable Old Worlds: reclusive and docile by baboon standards, no urticating hairs, happy dry. Rare in the UK and priced accordingly (£70 for CB females), but genuinely one of the best 'first African Old World' candidates for keepers wanting webbing behaviour without earth-tiger attitude.

Care Guide
Harpactira baviana
Purcell's Baboon - a complete husbandry sheet. Use as a starting point and adjust to your individual specimen.
What size enclosure does a Purcell's Baboon Tarantula need?
Adults
25 × 20 cm footprint with 10 cm of dry substrate for the tunnel system.
Slings & Juveniles
Small tubs with 6-8 cm of dry substrate and a starter anchor.

What temperature and humidity does a Purcell's Baboon Tarantula need?
Heating
The Purcell's Baboons is comfortable at 23-27 °C. UK homes need gentle supplementary warmth for much of the year; warm the room, never the tank floor.
Humidity
50-60 %: dry substrate, full water dish. Karoo husbandry - drier is better.
Ventilation
Cross-ventilation with a dry setup - semi-arid species need airflow, not humidity.
What substrate is best for a Purcell's Baboon Tarantula?
Recommended Mixes
Depth
10-12 cm
Notes
Deep and dry-packed, holding tunnel structure. A moisture gradient is unnecessary; keep the dish full instead.
How do you set up a Purcell's Baboon Tarantula enclosure?
Décor
The Hide
Its own silk tunnel system - cork bark and deep substrate become the scaffolding for an elaborate tube web.
Water
Always provide a shallow water dish at the tube mouth.
Lighting
No special lighting needed. Ambient room light is enough.
How often should you feed a Purcell's Baboon Tarantula?
Good Feeders

Is my Purcell's Baboon Tarantula dying or moulting?
Pre-moult signs to look for
Refusing food for weeks is normal before a moult - a healthy Purcell's Baboon Tarantula fasting is almost never an emergency in itself. Watch for slowing down and spending more time in the hide, laying a thick moult mat of web on the floor. Old World species do not flick urticating hairs, so there is no bald patch to watch - rely on fasting, lethargy and hide time instead.
On its back is MOULTING, not dying
A Purcell's Baboon Tarantula lying upside down or on its side with legs curled inwards is almost certainly mid-moult. Do not touch it, do not right it, do not mist it - just remove any live prey (crickets can kill a defenceless moulter) and leave the room.
How long between moults?
For this species, expect a moult roughly every 24-48 days for spiderlings, every 60-100 days for juveniles, and every 140-220 days for sub-adults, with adult females moulting around every 10 months (up to 14.3 months at the extreme). Males never moult again after their ultimate (mature) moult.
After the moult: fang hardening time
The new exoskeleton stays soft, with fangs that cannot grip, for roughly 7 days in this species. Offer no food and no handling for about 7 days - feeding too early is how fresh moulters get injured. The shed exuvium is also the best sexing tool there is - see our tarantula sexing guide for what to look for.
Genuinely worried about behaviour that is not moulting? Our "Is my T okay?" triage tool walks the danger signs one by one.
What ongoing care does a Purcell's Baboon Tarantula need?
🪞 Moulting
Moults inside the web tunnel, usually sealed in. Do not open the system; keep the water dish full and wait until it reopens with hard black fangs before feeding. Adult intervals apply to mature FEMALES - a mature male never moults again.
🧹 Cleaning
Weekly: refresh the water dish and clear boluses from the tube mouth. Full clean rarely.
✋ Handling
Docile for a baboon but still an Old World with a real bite - observe, catch cup for moves.
What are the most common mistakes when keeping Purcell's Baboon Tarantulas?
✓ What They Love
- Dry semi-arid setup with a full water dish
- Deep substrate for tunnel systems
- Cross-ventilation
- Anchor points for the web tube
- Watching the architecture grow nightly
✕ Common Mistakes
- Wet substrate - Karoo species
- Free handling - still an Old World baboon
- Shallow substrate - the tunnels are the point
- Expecting it out in daylight
