Scorpions have eight legs like 

 spiders, but do not spin ; their 

 abdomen is composed of several 

 jointed rings, and is furnished 

 with a recurved hook with which 

 they can pierce the skin of an 

 animal, injecting into the wound 

 a venom which causes great pain. 

 These animals are not found in

 generally come out at night. 

 They only use their dart when 

 irritated.
