Other key changes from the First Edition (1990) include:
* the incorporation of new developments in phylogenetics, developmental biology, and molecular genetics * major changes at the highest levels among the invertebrates. Three phyla that appeared in the original book?Pentastomida, Pogonophora, and Vestimentifera?no longer exist, and a new phylum, Cycliophora, has been erected. Moreover, this edition discusses recent work in molecular systematics that has shaken classic views on animal classification. * a large new section on "Kingdom Protista" (replacing "Protozoa") containing new contemporary views of these organisms (arranged in 18 phyla).
There is ample material in this book for any most groups of invertebrates. This book would work well for an undergraduate or a graduate level course. The line drawings and BW photos are great. The text is well written, and comprehensive taxonomic information is included.
I hope Brusca and Brusca come out with a 2nd edition, since this book was published ten years ago. If they do, it will be a top candidate for my invert zool course in the future.
5 stars.
