Other common names: OBT; Usambara Orange Baboon Tarantula; Mombassa Golden Sunburst Tarantul; Golden Starburst Tarantula; True Starburst Tarantula; Orange Demon Spider
Scientific name: Pterinochilus murinus
The Orange Baboon Tarantula is native to the Usambara region of Kenya, Africa. OBT's are nocturnal, semi-arboreal tarantulas, meaning they burrow and also spend time in higher areas. They are considered to be very aggressive, quick, and highly defensive spiders.
Appearance / health:
The Usambara Orange Baboon has a distinctive starburst pattern on its back. This starburst pattern is made up by golden or yellow hairs with a background color of black or very dark brown. The abdomen is covered in hairs that range from yellow, olive, and brown colors. They display a mustard-like color. The legs have white tufts of hairs on all the leg joints with a yellow or golden line running the length of the legs. This tarantula is average size, only getting about 4-5 inches.
Behavior / temperament:
Orange Baboon Tarantulas are very fast tarantulas and tend to be skittish and show high aggression levels. Some people have called them “balls of fire” since they are a reddish orange color and move very quickly. These are not recommended for beginners.
The cage size for these tarantulas can be anything from 10 gallons or more. These tarantulas are very, very fast and it’s recommended that they are fed by sliding tongs inside through a very small hole, or dropping its food inside the tank without opening the top all the way.
Temperatures and humidity levels for this tarantula need to be kept up. Temps should be 70-80F and humidity levels should be around 65-70%. The humidity should never fall below 60% so keep an open shallow water dish inside the tank. Provide other tank décor that will allow this tarantula to hide and/or climb if it wishes. Since it likes to burrow a lot, a deep substrate is a must. A mix of peat moss and vermiculite about 5-8 inches will be okay. They are heavy web spinners and will web most of their cage making web tunnels.
They will accept anything from crickets, mealworms, locust, grasshoppers, and other small invertebrate feeders.

"Pterinochilus murinus is one of the fastest, most aggressive spiders in the world. It is also the most beautiful. Even the slings are a vibrant orange with tiny, iridescent turquoise "feet". <br><br>Feeding is easy -- drop in a cricket (pinheads for slings), and enjoy. However, be sure the fangs stay in the insects and don't go into you -- Old World tarantulas, like these, have some of the strongest venom in the tarantula world. It will not kill (in fact, no one has ever died from a tarantula bite -- ever!) but Old World spider bites can cause horrible pain and muscle spasms. <br><br>Given their speed and fragility, it is important to keep these spiders in careful accommodations so they do not bolt out of the cage and injure themselves in the process. They are challenging, but utterly beautiful. Although I have never bred them myself, they also breed readily and are a good starter species for breeding!."

"I know everyone says these guys are difficult to keep, but they are so worth it! I have kept a few the past few years, and not only are they invincible little devils, they are so much fun. Yes, they are incredibly aggressive, but that mixed with their high level of energy makes them exciting to watch, especially during feeding time. They make an absolute artwork out of their enclosure, tunneling through it all over the place and coating the tunnels with thick webbing. Its fun guessing where theyre going to emerge from to catch their prey during feeding time. Another fun feature about them is the variation of oranges they come in when keeping numerous spiders. They always look different from one another. As shown in the photo I posted with the review, the underside of their legs are stunning. Though I agree with the other reviewers and would not recommend this species to a beginner keeper, I WOULD recommend them for a beginner BREEDER. They are surprisingly easy to mate compared to other breeds, even if you do have to make sure they don't kill each other once theyve successfully mated. ."

"This isn't a pet. It is something people should only see in some sort of professional environment. They are beautiful to look at and even more amazing to watch. This was the most graceful and amazingly fast taratula's I have ever seen. It is a dangerous tarantula to own. I am from Oklahoma and we have native taratulas that are very docile and can be held and played with. Do not ever attempt to play with one of these tarantulas. I opened the lid to the aquarium to feed once, keep in mind this takes only a second, the thing jumped for it. It was out before I could see which direction it went. We were lucky it was caught and put away, but during the challenging hunt to capture it aggression came out. This is a very aggressive creature. Only walking by the aquarium is enough reason for it to stand up in threat, just imagine trying to catch that! I cannot describe the speed or the length of its jump. This is a very aggressive and athletic tarantula that shouldn't be owned by the common pet owner.."
