Presenting a broad overview of current trends and recent research, this book discusses such groups as sponges, ctenophores, rotifers, annelids, and pogonophores. The book's assessment of lower invertebrates include investigations of reproduction and larval development relevant to phylogeny, problems of pseudocoelomate evolution, and the fossil record of lower invertebrates.
