Just browsed this on Amazon. The first thing I noticed is that Crutchfield's name is misspelled on the copyright page.
An oddly organized book -- ostensibly about snakes that are large, but actually about pythons and boas (many of which are small). It isn't clear how much of Chapter 3 even supports the central topic; for example, an extended discussion of the genetic sex determination system of snakes doesn't serve to inform about giant snakes as such. Seems the author decided to wing this one without an editor.
Looks like there is a ton of really interesting information there, though.
