Pagoo is one of my favorite children/science books. Holling Clancy Holling is a wonderful author and created a series of great books for children, as well as adults, you will both learn so much! All of his books take you on a journey or life story of the main character, in this case Pagoo(abbreviated from the correct biological name) is the life story of a hermit crab. I used to read one page a night to my boys, and one page alone is filled with so much information and illustrations you'll see why. I swear both my boys, now young men, have a tremendous sensitivity to the earth and all its creatures and I believe some of this was because of the wonderful perspective Holling Clancy Holling gave them. We read all of his books, but Pagoo, Minn of the Mississippi(a female snapping turtle's tale) and the most famous Paddle to the Sea(the journey of a small wooden Indian in a canoe) were our favorites!
