The name black widow strikes fear into hearts of those living where these spiders reside. These fearsome arachnids have venom about 15 times more powerful than that of a rattlesnake! With their distinctive black bodies and red mark on their abdomens, black widows terrorize those afraid of spiders and their poisonous bites. This book explores how these creatures live, where to find them, and what they use all that venom for. It also gives readers a look at why these spiders are so feared, and what to do if they bite humans.
