The book was written as ""a brief summary of some of the presently accepted facts and of the interpretations that can be placed on them."" The author is at particular pains to explode the old wives' tales and misinformation that have grown up around snakes for centuries. He is brief and his chapters proceed from origins and evolution through senses, locomotion, feeding and breeding to specific families of snakes. There are line drawings throughout and some photographs. An appendix lists the antivenins for snake bite.
