Socotra Island Blue Baboon (Monocentropus Balfouri)

The Socotra Island Blue Baboon (Monocentropus balfouri) is a legend in the tarantula world. 🔥 This species is both gorgeous and wildly unique in behavior. It’s not just a looker — it’s also one of the few tarantulas known for communal living. Let’s dig in:

Quick Facts

• Common Name: Socotra Island Blue Baboon

• Scientific Name: Monocentropus balfouri

• Origin: Socotra Island, Yemen — super remote, exotic locale

• Size: 5–6 inches (12–15 cm) leg span

• Lifespan:

  • Females: 10–15 years

  • Males: ~3–4 years

• Temperament: Defensive, not for handling, but often reclusive

• Coloration: Light creamy body with electric blue legs and sometimes blue striping on the carapace — one of the most beautiful tarantulas out there

Housing

• Enclosure Type: Fossorial (deep burrowers) but will also web like mad

• Substrate: Deep (4–6") layer of coco fiber, topsoil, or a mix — give them digging room

• Humidity: ~60–70% (dry side is okay with a water dish)

• Temperature: 75–80°F (24–27°C)

• Decor: Cork bark tubes, leaf litter, and anchor points for webbing — they’ll build epic tunnels

✅ Communal setups are possible with this species only if done carefully and with siblings raised together. Cannibalism is still a risk but way lower than with most species.

Feeding

• Diet: Crickets, roaches, mealworms

• Feeding Frequency:

  • Slings: 2–3 times/week

  • Juveniles: Weekly

  • Adults: Every 10–14 days

  • Communal setups can take down larger prey together!

Caution

• Fast and defensive — not ideal for beginners or handling

• Quick to retreat to burrows but will throw a threat pose if provoked

• Rehousing can be intense due to their speed and feistiness
