URBAN TARANTULAS
Orange Baboon Tarantula
Pterinochilus murinus · OBT

The Orange Baboon Tarantula is famous for a combination that is hard to forget: blazing orange coloration, incredible webbing, serious speed, and plenty of defensive attitude. This is a tarantula for collectors who appreciate the spicy side of the hobby. Give an OBT room to build, and it can transform its enclosure into an out-of-this-world maze of silk.

Special Notices

Bring your respect for spicy species. OBTs are extremely fast and can be strongly defensive when disturbed, so secure enclosures, thoughtful maintenance, and giving the tarantula space are especially important.

Care Details

🌡️ Temperature: A comfortable room-temperature range around 72–80°F (22–27°C) works well. Avoid prolonged extremes and focus on stable conditions rather than adding unnecessary heat.

💧 Humidity: Keep this species on the drier side with good ventilation. Slings benefit from some moisture in part of the substrate, while larger specimens can be maintained mostly dry with a water dish and occasional localized moisture rather than a constantly damp enclosure.
🏠 Housing

Babies / Slings: Use a secure, ventilated sling enclosure with enough substrate for digging and several anchor points. Expect webbing early, and provide small prey while keeping part of the substrate lightly moist.

Juveniles: Provide a secure terrestrial setup with generous substrate, a starter retreat, water, ventilation, and plenty of cork, foliage, or other safe anchor points. Juveniles can quickly turn the enclosure into a dense web fortress.

Adults: House terrestrially with ample substrate for excavation, limited fall distance, a retreat, water dish, strong ventilation, and abundant web anchors. Plan maintenance around the spider's speed and extensive webbing rather than routinely disturbing its structure.
🍽️ General Diet

Offer appropriately sized crickets or suitable roaches such as Dubia, Red Runner, or Lobster roaches. Slings can take small live prey or appropriately sized pre-killed prey when necessary, with prey size adjusted to the individual tarantula.

Adjust feeding according to life stage and body condition rather than forcing a rigid schedule. Remove uneaten prey and boluses when practical, and avoid leaving live prey with a tarantula preparing to molt.
