Book Description
Bizarre creatures are floating around in our oceans—squishy, slimy, spiky-headed monsters. And they're not even grown up yet! These kids have to go through some drastic changes before they get to be adults. Everyone knows that caterpillars and tadpoles go through metamorphosis, but so do some of the most monstrous creatures under the sea. Take the spiky-headed zoea, somersaulting through the water on her way to becoming a blue crab. Or the gnathiid larva that sucks the fluid right out of a fish's eyeball through his needle-like mouth. That is, until he's full enough to become an adult that doesn't eat anything. Or the moon jellyfish that starts off as a small, orange blob and eventually plants itself on the seafloor and produces not one but many adult jellyfish. Dive deep with these little monsters of the ocean to follow along as they go through drastic changes on their way to growing up.

Book Description
Many biological facts are irreconcilable with the assumption that larvae and adults evolved from the same genetic stock. The author of this book draws attention to these, and presents his alternative hypothesis that larvae have been transferred from one taxon to another. In his previous book (Larvae and Evolution, 1992), the author used larval transfer to explain developmental anomalies in eight animal phyla. In the present book, he claims that the basic forms of all larvae and all embryos have been transferred from foreign taxa. This leads to a new, comprehensive theory on the origin of embryos and larvae, replacing the discredited 'recapitulation' theory of Haeckel (1866). Metamorphosis, previously unexplained, represents a change in taxon during development.

Book Description
Current Topics in Comparative Pathobiology, Volume 2 covers several areas of pathobiology. The book discusses the biology of trematodes of the genus Paragonimus that occur in the Americas; the milky disease of beetles; and the biochemical exploration in insect pathology. The text describes the application of invertebrate tissue culture to the in vitro study of animal parasites; and the use of hydra-hydramoeba as a model system for the study of epizootic processes. The aspects of the biology of nudibranchs are reviewed, with emphasis on nudibranchs as members of associations, including functional morphology, physiology, utilization of host pigments and nematocysts, life history, behavior, defensive mechanisms, and ecology. Chemists, bacteriologists, parasitologists, invertebrate pathologists, immunologists, and protozoologists will find the book invaluable.

Book Description
This richly illustrated book presents the diversity and natural history of sea snail groups. By integrating aspects of morphology, ecology, evolution and behaviour, it describes how each group copes with problems of defence, locomotion, nutrition, reproduction and embryonic development. First come general characteristics of the Mollusca, to which snails belong; and next, characteristics by which snails (Gastropoda) differ from other molluscs. Then a broad, panoramic view of all major sea snail groups, from the primitive to the more advanced, is presented, including both the more abundant and some remote ones of special interest. In detailing primitive sea snails, first limpets (Patellogastropoda) are described, followed by brush snails (Vetigastropoda: top-shells, turbans and allies) and nerites (Neritimorpha), a small group with remarkably high variation in shell colour and in habitats. In looking at advanced-snails (Caenogastropoda), it details the herbivorous grazers and filter-feeders and the many voracious predators, some which use venomous darts. The book also covers sea slugs (Opisthobranchia), which have shifted from mechanical to chemical defence; some are herbivores, some use their food to harness solar energy, others are predators that gain stinging cells and poisonous compounds from their food. In addition, readers will learn about aspects of sea snails in human culture, including use as sacred artefacts and objects of magic and money, as a source of the royal and sacred dyes of purple and blue and as holy ceremonial trumpets. The text, in which scientific terms are accompanied by parallel common ones, is accompanied by over 200 illustrations (mostly in colour). This comprehensive, insightful portrait of sea snails will appeal to marine biologists, zoology lecturers and students, biology teachers, field-school instructors, nature reserve wardens, amateur naturalists, as well as to lecturers and learners of human culture.
