Bottom Feeders

It is entirely possible that I am the only one that didn't know about the Deep Web. Admittedly I had heard a few things but not enough to cause me to look into it, that is until it came up in a book I'm reading. The facts aren't quite right in the book but since it's fiction that is to be expected. I feel naive for never thinking about there being many layers to the World Wide Web, the way it was explained in the book is thinking of a search engine as a fishing net and on the surface are spiky balls that are easy to net,below those are tennis ball which are harder to net but not impossible,further down are billiard balls which are not only heavier but also slick and nearly impossible to get into the net. In the book the Deep Web is made to seem nefarious and nearly impossible to access, but if you want to download special software it can be done. There is also a Dark Web which sounds particularly forbidding but from what I found is mainly a way of obtaining privacy in areas where it isn't offered on the regular Web,and of course most all of the bad stuff a person can imagine can be found on any of the many levels of the internet.
