About the blue baboon tarantula

Pterinochilus murinus, widely known as the orange baboon tarantula, is a nocturnal spider found in Angola and across central and southern Africa, including Zanzibar. Females grow to 10 to 15 cm in leg span and males to 7.5 to 10 cm. Coloration ranges from red to orange and brown, with brightly ringed legs, a star-shaped pattern on the carapace and no urticating hairs. Females dig a burrow or take over an abandoned one. It is highly defensive and often bites without a warning display; the bite is not serious but extremely painful, and its colour forms are thought to relate to local soil.

AZAThe Association of Zoos and Aquariums. Accredited members have passed an independent inspection of animal care and welfare, safety, conservation and education, repeated every five years. Many smaller facilities never apply, so “not accredited” isn't a verdict on its own. What accreditation means · How we check this
