Grzimek's Animal Life Encyclopedia: Protostomes Vol. 2

 H. C. Bernhard Grzimek hoped his original encyclopedia would "disseminate knowledge of the animals and love for them." This is also a goal of the revised edition; it does not disappoint. All volumes follow a similar organization. Introductory chapters, written in a narrative style, are usually followed by taxonomic chapters and species accounts, which follow a prescribed format.
