Fig. 11-48. The common scorpion (Ve/ovis) of the Southwest is an arachnid like the spider. It hides by day and 

 hunts spiders and insects at night. The sting at the tip of the tail is an effective weapon against predators and is 

 useful in capturing prey. It sucks the body fluids from its prey. Its sting is painful to humans but not fatal.
