I only read the part about Scorpions, due to the fact that I don't think I will ever want to own a large, hairy spider and would much rather own a scorpion (although some quite spider-like relatives of the scorpion don't look too shabby either- see camel spiders and whipscorpions). I didn't find too much specific information in this book- they only dedicate 10 pages to scorpions in the whole book- but it was a really awesome introduction to scorpion-keeping. Not to mention that the authors warned you almost every other paragraph NOT TO BE AN IDIOT AND HANDLE YOUR SCORPION. I thought that was pretty funny.
