A book about the different kinds of spiders and what the do for humans. I liked how there was a story to follow as I learned about the different types of spiders. I learned a lot about them. I never knew there were so many different types. Each has their own look as well as their own living conditions. I always thought they all spun webs like you see in corners of rooms but they don't. I liked that photographs were shown. This is perfect for your 4-8 year old as well as adults.
