Pterinochilus murinus, often called the Orange Baboon Tarantula or simply “OBT,” is one of the hobby’s most recognizable species. Native to eastern Africa, it is famous for its bright orange colouration, lightning-fast speed, and dramatic defensive displays. Despite its intimidating reputation, OBTs are fascinating spiders that spend much of their time creating dense web tunnels throughout the enclosure. Unlike New World tarantulas, they lack urticating hairs and rely on speed and threat postures for defence. Their hardy nature and incredible webbing make them rewarding to observe, though their defensive temperament means they are usually recommended for experienced keepers rather than beginners.
Orange Baboon Tarantula Care Guide
The Orange Baboon Tarantula, commonly called the OBT, is one of the most infamous tarantulas in the hobby. Known for its vivid orange colouration, intense webbing, and defensive attitude, this species is both beautiful and intimidating. While not ideal for beginners, experienced keepers often love them for their bold personality and fascinating behaviour.
Temperament
OBTs are extremely fast, defensive, and highly reactive. Unlike New World species, they do not possess urticating hairs and may stand their ground when threatened. They are best appreciated as display animals rather than handled pets.
Enclosure Setup
This species thrives in a dry, well-ventilated enclosure with plenty of anchor points for webbing. Cork bark, branches, and hides work especially well. They will quickly create thick web tunnels across the enclosure.
A deep layer of dry substrate is recommended, especially for younger specimens that enjoy burrowing.
Temperature & Humidity
- Temperature: around 24–28°C
- Humidity: low to moderate
- Ventilation: very important
Avoid excessive moisture, as OBTs prefer arid conditions.
Feeding
OBTs are aggressive feeders and rarely refuse prey. Crickets, roaches, and locusts are all suitable feeder insects. Juveniles usually eat weekly, while adults can be fed every 1–2 weeks.
Webbing
This species is an exceptional webber. Many keepers consider the elaborate tunnel systems and silk-covered enclosures one of the most rewarding parts of keeping an OBT.
Lifespan
Females may live 10–12 years, while males usually live only a few years after maturity.
Final Thoughts
The Orange Baboon Tarantula is a stunning and fascinating species best suited for confident keepers comfortable with fast and defensive spiders. With proper respect and secure housing, they can make incredible display animals.
