Mombasa Starburst Baboon Tarantula. The baboon spider Pterinochilus murinus, an old world tarantula, was first described in 1897 by Reginald Innes Pocock. This species is found on the African continent, in Angola, as well as central, eastern, and southern Africa. This species is incredibly defensive and should not be held. The bite of this species is extremely painful. The species is more than willing to inflict such a bite before presenting the typical threat display.
Among those who keep tarantulas as pets Pterinochilus murinus is known as OBT, which means Orange Baboon Tarantula or Orange Bitey Thing, and also as the Pterror, a pun on its Latin genus classification of Pterinochilus. These nicknames reference a particular orange color form that is prized in the hobby for its beauty and confrontational personality. It is also known as the Mombasa golden starburst tarantula.
