Desert Hairy Scorpion

Desert Hairy Scorpion
Hadrurus arizonensis

Our resident desert hairy scorpion is Yuma, who came to us in 2018. Yuma is a close relative of the scorpion found here in the Bay Area, the Western or California forest scorpion. Desert hairy scorpions are much larger, reaching over 5 inches long while our local scorpions are only about 1.5 inches in length. Yuma’s size allows visitors to see all the amazing adaptations of scorpions — including their pointy tails — at a larger scale. Although his tail is mildly venomous, Yuma only uses it to pierce his prey: crickets. Scorpions are primarily insectivorous but in the wild they will also go after vertebrates like small mice and lizards.
