This book gathers current data on the two types of fish metamorphoses and their endocrine controls. It will be of interest for fish biologists as well as comparative physiologists and endocrinologists. Metamorphosis is a major developmental phase characterized by morphological and physiological changes. It prepares organisms for a drastic shift in habitat and behavior. Among vertebrates, besides the well-known larval metamorphosis in amphibians, two types of metamorphosis are also described in the life cycle of some fish species. Larval metamorphosis, also called first metamorphosis or true metamorphosis, is encountered in lampreys, representative species of basal vertebrates as well as in some teleost groups, elopomorphs and pleuronectiforms, and possibly also in some other teleost species. Secondary metamorphosis occurs in juveniles of some diadromic migratory teleosts, such as salmons and eels, and compared to larval metamorphosis, involves less drastic morphological changes.

Insect Metamorphosis: From Natural History to Regulation of Development and Evolution explores the origin of metamorphosis, how it evolved, and how it is it regulated. The book discusses insect metamorphosis as a key innovation in insect evolution. With most of the present biodiversity on Earth composed of metamorphosing insects—approximately 1 million species currently described, with another 10-30 million still waiting to be discovered, the book delves into misconceptions and past treatments. In addition, the topic of integrating insect metamorphosis into the theory of evolution by natural selection as noted by Darwin in his On the Origin of Species is also discussed. Users will find this to be a comprehensive and updated review on insect metamorphosis, covering biological, physiological and molecular facets, with an emphasis on evolutionary aspects. - Features updated knowledge from the past decade on the mechanisms of action of juvenile hormone, the main doorkeeper of insect metamorphosis - Aids researchers in entomology or developmental biology dealing with specialized aspects of metamorphosis - Provides applied entomologists with recently updated data, especially on regulation, to better face the problems of pest control and management - Gives general evolutionary biologists context on the process of metamorphosis in its larger scope

We are all fascinated by the mystery of metamorphosis – of the caterpillar that transforms itself into a butterfly. Their bodies have almost nothing in common. They don’t share the same world: one crawls on the ground and the other flutters its wings in the air. And yet they are one and the same life. Emanuele Coccia argues that metamorphosis – the phenomenon that allows the same life to subsist in disparate bodies – is the relationship that binds all species together and unites the living with the non-living. Bacteria, viruses, fungi, plants, animals: they are all one and the same life. Each species, including the human species, is the metamorphosis of all those that preceded it – the same life, cobbling together a new body and a new form in order to exist differently. And there is no opposition between the living and the non-living: life is always the reincarnation of the non-living, a carnival of the telluric substance of a planet – the Earth – that continually draws new faces and new ways of being out of even the smallest particle of its disparate body. By highlighting what joins humans together with other forms of life, Coccia’s brilliant reflection on metamorphosis encourages us to abandon our view of the human species as static and independent and to recognize instead that we are part of a much larger and interconnected form of life.

In an age when advanced molecular and genetic tools allow studies in various systems, amphibian metamorphosis still offers perhaps the most accessible model for the study of postembryonic organogenesis and mechanisms of hormonal regulation during vertebrate development. Amphibian Metamorphosis: From Morphology to Molecular Biology integrates findings from the most recent research with earlier observations, providing molecular and mechanistic insights into the signal transduction pathways underlying tissue-specific transformations during metamorphosis. The author, renowned expert of anuran metamorphosis and Head of the Unit of Molecular Morphogenesis at NICHD/NIH, begins with an overview of metamorphosis in different classes of amphibians and various factors that influence this process. A review of earlier morphological, cellular, and biochemical changes focuses on organs and tissues that have been studied extensively at the molecular level, while discussion of the thyroid hormone signal transduction pathway emphasizes transcriptional regulation mechanisms by thyroid receptors. The book provides a summary and comparison of gene regulation programs induced by thyroid hormone in several organs that undergo distinct metamorphic transformations. Several chapters are devoted to functional and mechanistic implications of the molecular findings on the thyroid hormone response genes in tissue transformation. Special features of this book include: * An emphasis on integrating the morphological approach with molecularand cell biology * A historical perspective on the progression from discovery of the thyroid hormone to present-day research advances * Comparisons of amphibian and insect metamorphosis * Dozens of instructive photographs, several in full color Amphibian Metamorphosis: From Morphology to Molecular Biology is a unique and invaluable resource for professionals and aspiring professionals in develop-mental biology, molecular biology, cell biology, evolutionary biology, and endocrinology.

Franz Kafka, the author has very nicely narrated the story of Gregou Samsa who wakes up one day to discover that he has metamorphosed into a bug. The book concerns itself with the themes of alienation and existentialism. The author has written many important stories, including ‘The Judgement’, and much of his novels ‘Amerika’, ‘The Castle’, ‘The Hunger Artist’. Many of his stories were published during his lifetime but many were not. Over the course of the 1920s and 30s Kafka’s works were published and translated instantly becoming landmarks of twentieth-century literature. Ironically, the story ends on an optimistic note, as the family puts itself back together. The style of the book epitomizes Kafka’s writing. Kafka very interestingly, used to present an impossible situation, such as a man’s transformation into an insect, and develop the story from there with perfect realism and intense attention to detail. The Metamorphosis is an autobiographical piece of writing, and we find that parts of the story reflect Kafka’s own life.

Nonhuman figures are ubiquitous in the work of Franz Kafka, from his early stories down to his very last one. Despite their prominence throughout his oeuvre, Kafka’s animal representations have been considered first and foremost as mere allegories of intrahuman matters. In recent years, the allegorization of Kafka’s animals has been poetically dismissed by Kafka’s commentators and politically rejected by posthumanist scholars. Such critique, however, has yet to inspire either an overarching or an interdiscursive account. This book aims to fill this lacuna. Positing animal stories as a distinct and significant corpus within Kafka’s entire poetics, and closely examining them in dialogue with both literary and posthumanist analysis, Kafka’s Zoopoetics critically revisits animality, interspecies relations, and the very human-animal contradistinction in the writings of Franz Kafka. Kafka’s animals typically stand at the threshold between humanity and animality, fusing together human and nonhuman features. Among his liminal creatures we find a human transformed into vermin (in “The Metamorphosis”), an ape turned into a human being (in “A Report to an Academy”), talking jackals (in “Jackals and Arabs”), a philosophical dog (in “Researches of a Dog”), a contemplative mole-like creature (in “The Burrow”), and indiscernible beings (in “Josefine, the Singer or the Mouse People”). Depicting species boundaries as mutable and obscure, Kafka creates a fluid human-animal space, which can be described as “humanimal.” The constitution of a humanimal space radically undermines the stark barrier between human and other animals, dictated by the anthropocentric paradigm. Through denying animalistic elements in humans, and disavowing the agency of nonhuman animals, excluding them from social life, and neutralizing compassion for them, this barrier has been designed to regularize both humanity and animality. The contextualization of Kafka's animals within posthumanist theory engenders a post-anthropocentric arena, which is simultaneously both imagined and very real.
