Adult female
Pterinochilus murinus, commonly known as the Orange Baboon Tarantula (or OBT), is a striking Old World species famous for its brilliant orange coloration and notorious defensive temperament. Native to various countries in central and southern Africa, including Angola, Burundi, Congo, Kenya, Malawi, Tanzania, Zambia, and Zimbabwe, this tarantula is technically terrestrial but often displays semi‑arboreal behaviors in captivity. Due to its speed, aggression, and medically significant venom, it is best suited for advanced keepers who can provide a secure, well‑designed enclosure.
