Foelix goes in to great detail about the anatomy of spiders. You learn about all the different parts of the body, on the inside and the outside.

You learn about everything from their lungs to their nervous system. For some unknown reason, the brain is pretty much glossed over.

Chapters 2 through 4 - Functional Anatomy, Metabolism, Neurobiology- were a little bit difficult for me to get through. They read like a biology text book for college. I was not a science major and some of this was written way too formal.

Like, a lot of big science words that I had no clue what they meant because there was no explanation. This book was marked as a great book for people who just liked spiders, but it felt like you also had to have a degree in biology in order to understand some of it. Then one of them says "This book reads like stereo instructions From chapter 5 and on, the book really picked up. Or, it was just more of what I was looking for in the book. These chapters were really good!

They had less of the big biology terms and dealt more with behaviors and habits. Cells, microscopes, tissues, glands, and so on I have always had a hard time figuring that stuff out. But behavior, psychology and evolution are a few of the sciences I am good at. Also, a lot of the questions I had about spiders came from this section of the book.

It was really fascinating learning about how spiders build their webs, or how some spiders take care of their young. I really learned a lot of good stuff and just about all my questions were answered. There were plenty of pictures to look at. You had microscopic things like cell tissue and organs.

I thought they always just looked like spiders, but, you know And there were plenty of shots of spiders doing things, like caring for their young or hunting. While I did enjoy seeing the photos, some times it was a little bit hard to see them clearly because they were old black and white shots and sometimes things just blended in too much with backgrounds or surrounding items.

There were also numerous illustrations. Mostly the illustrations showed us how the body worked. Things like organ placement or leg movement. All the illustrations were very clear and well drawn. Both the photos and the illustrations all had very helpful captions that explained, sometimes in great detail, about what you were looking at.

Biology of Spiders is an extremely detailed book about spiders. Each time close to a new pages of brand new spider info was added, as well as several corrections on old or outdated info.

This was a very fascinating book for a spider fan. While some of the chapters felt more like a text book lecture, there was a lot to learn from Biology of Spiders.

There were a lot of amazing photographs and clear illustrations to show you what the book was talking about. While not all my questions were answered, this was a great book to read and I really enjoyed learning more about my little spider friends.
