I can not recomment this book highly enough. It should be in the library of every school and university and I think all biologists would benefit from having a copy in their personal collection.

Walker, Journal of Biological Education, 2002 This edition of a very useful text contains new research adding to our knowledge of invertebrates, and ... Read moremany chapters have been updated and rewritten. [...] Zoology students will welcome this new edition. (Aslib Book Guide, Dec 2001) Essentially, this is a simple text. It aims to bring together all invertebrates and describe them in terms of their differences (phyla) and common elements (functions). Although the text needs to be precise, it is clear and the diagrams are very good. This is an excellent reference text which should find its way into field centres and school/college libraries. (TEGNews, Dec 2001) When it comes to the invertebrates the position is much less clear cut. There are many gaps in our knowledge and so often the evolutionary relationships between the phyla are neglected. It is also a difficult area of zoology because many of the key organisms are unfamiliar ones, but in this book the subject is dealt with very clearly. It is a bold step to put it at the beginning, because there are many unfamiliar terms and concepts not covered until later in the book, but I think it works, not least because it gives the subject the importance it deserves. The book ought to become the standard text for invertebrate courses. (New Scientist, Sept. 1993) ... a good student
