I bought this book when I knew I would be going out to Sri Lanka for my son's wedding.
It is a small pocket sized paperback in full colour with 143 pages mostly in colour with some black and white line drawings.
The book includes maps of Sri Lanka, a full checklist of species, chapters on climate , landscape and vegetation, conservation, protected areas of Sri lanka, snakebite and its management(hopefully you will never have to use this bit-but read it anyway just in case.....
The photo's are excellent and there is a full index of species listing all snakes lizards and chameleons etc found throughout the islands.
You don't always get a long look at snakes in the wild, they are usually aware of you before you are aware of them so when I do find one I immediately take a photo and then you can read through this book back at base to confirm what you have seen.
One small criticism is that the book does not always state clearly if a species is venomous or not and if you enjoy handling snakes as I do it is best not to chance anything unless you are 100% certain of the species-it may just be because some species though identified may not have been tested for venom which is best left to experts in the field.
All in all and excellent little book for the interested and experts alike.
