Available in PDF, EPUB and Kindle. Book excerpt: Interest in land crabs has burgeoned as biologists have increasingly focused on the evolution of terrestriality. Before the publication of this volume in 1988, there had been no single comprehensive source of information to serve biologists interested in the diverse aspects of terrestrial decapod crustacean. Biology of the Land Crabs was the first synthesis of recent and long-established findings on brachyuran and anomuran crustaceans that have evolved varying degrees of adaptation for life on land. Chapters by leading researchers take a coordinated evolutionary and comparative approach to systematics and evolution, ecology, behaviour, reproduction, growth and molting, ion and water balance, respiration and circulation, and energetics and locomotion. Each discusses how terrestrial species have become adapted from ancestral freshwater or marine forms. With its extensive bibliography and comprehensive index, including the natural history of nearly eighty species of brachyuran and anomuran crabs, Biology of the Land Crabs will continue to be an invaluable reference for researchers and advanced students.

Available in PDF, EPUB and Kindle. Book excerpt: The world’s nearly 7,000 species of crabs are immediately recognizable by their claws, sideways movement, stalked eyes, and thick outer shells. These common crustaceans are found internationally, thriving in various habitats from the edge of the sea to the depths of the ocean, in fresh water or on land. Despite having the same basic body type as decapod crustaceans—true crabs have heavy exoskeletons and ten limbs with front pincer claws—crabs come in an enormous variety of shapes and sizes, from the near microscopic to the giant Japanese spider crab. In Walking Sideways, Judith S. Weis provides an engaging and informative tour of the remarkable world of crabs, highlighting their unique biology and natural history. She introduces us to recently discovered crabs such as the Yeti crab found in deep sea vents, explains what scientists are learning about blue and hermit crabs commonly found at the shore, and gives us insight into the lifecycles of the king and Dungeness crabs typically seen only on dinner plates. Among the topics Weis covers are the evolution and classification of crabs, their habitats, unique adaptations to water and land, reproduction and development, behavior, ecology, and threats, including up-to-date research. Crabs are of special interest to biologists for their communication behaviors, sexual dimorphism, and use of chemical stimuli and touch receptors, and Weis explains the importance of new scientific discoveries. In addition to the traditional ten-legged crabs, the book also treats those that appear eight-legged, including hermit crabs, king crabs, and sand crabs. Sidebars address topics of special interest, such as the relationship of lobsters to crabs and medical uses of compounds derived from horseshoe crabs (which aren’t really crabs). While Weis emphasizes conservation and the threats that crabs face, she also addresses the use of crabs as food (detailing how crabs are caught and cooked) and their commercial value from fisheries and aquaculture. She highlights other interactions between crabs and people, including keeping hermit crabs as pets or studying marine species in the laboratory and field. Reminding us of characters such as The Little Mermaid’s Sebastian and Sherman Lagoon’s Hawthorne, she also surveys the role of crabs in literature (for both children and adults), film, and television, as well in mythology and astrology. With illustrations that offer delightful visual evidence of crab diversity and their unique behaviors, Walking Sideways will appeal to anyone who has encountered these fascinating animals on the beach, at an aquarium, or in the kitchen.

Book excerpt: Horseshoe crabs, those mysterious ancient mariners, lured me into the sea as a child along the beaches of New Jersey. Drawn to their shiny domed shells and spiked tails, I could not resist picking them up, turning them over and watching the wondrous mechanical movement of their glistening legs, articulating with one another as smoothly as the inner working of a clock. What was it like to be a horseshoe crab, I wondered? What did they eat? Did they always move around together? Why were some so large and others much smaller? How old were they, anyway? What must it feel like to live underwater? What else was out there, down there, in the cool, green depths that gave rise to such intriguing creatures? The only way to find out, I reasoned, would be to go into the ocean and see for myself, and so I did, and more than 60 years later, I still do.

This book was released on 2021-02-10 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Study from the year 2021 in the subject Biology - Zoology, grade: A, Lagos State University (Nigeria), course: Fisheries and Aquatic biology, language: English, abstract: The objective of this study is to evaluate the domestication and the growth performance of the land crab (Cardisoma Armatum) cultured in a rectangular concrete unit. Crabs are part of the basic components of the ecosystem and they are consumed as food in many countries. Over 100 species of crabs are known worldwide with nine species common in West African countries especially Nigeria. Crabs are decapods crustaceans which have a very short tail and are covered with a thick shell, or exoskeleton and are armed with a single pair of claws. There are over 6,793 species of crab spread across the oceans, fresh water, and even on land. Among the species are the land crab, the big fisted swim crab (callinectes amnicola), and (callinectes latmanus). These 3 species are edible ones.Crabs mostly occur at the mouth of estuaries and along the course of many main rivers. Crabs which are the basic components of the ecosystem are the most advanced members of the phylum Arthropoda. The freshwater crabs of Nigeria are true crabs which can be distinguished from false crabs by not having 5 pairs of the pereiopods totally or partly concealed beneath the carapace, the antennae were always placed between the inner margin of orbit and fused Pterygostomial region with endotome. True crabs belong to the Suborder Brachyura of order Decapoda under Class Crustacea. It shows the greatest size range of all arthropods such as observed in lobsters, prawns, crayfishes, shrimps, hermit crab and true crabs.

Book excerpt: Crabbers should grab Philippe de Vosjoli manual on land hermit crabs for expert advice on keeping this popular and colorful invertebrate thriving in its vivarium! The popularity of hermit crabs is undeniable, as the author states in his introduction, "Their droll appearances and interesting behaviors have made them appealing to both children and adults looking for an affordable, low maintenance, and undemanding pet." Land Hermit Crabs seeks to inform dedicated hobbyists and casual crabbers alike about the requirements--minimal though specific--of land hermit crabs to keep their pets alive and healthy. Due to the low cost of hermit crabs, too many keepers carelessly allow their pets to die unnecessarily. The author says that the "high mortality of captive hermit crabs is [due to] the failure [of keepers] to provide a proper environment." This Advanced Vivarium Systems title provides detailed information on the selection of a health crab, housing, water and feeding requirements, molting, breeding, behavior, and health and other husbandry-related problems. Crab enthusiasts will also be interested to read about other crabs for freshwater aquaria in the final chapter, with photos of and information about fiddler crabs, red-clawed freshwater crabs, coconut crabs, and land crabs. Resources and index included.

This book was released on 2016-09-27 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sexual Biology and Reproduction in Crustaceans covers crustacean reproduction as it deals with the structural morphology of the gamete-producing primary sex organs, such as the testis and ovary, the formation and maturation of gametes, their fusion during fertilization, and embryonic development that lead to the release of larvae. Constituting a diverse assemblage of animals, crustaceans are best known by their common representatives, such as shrimps, lobsters, and crabs, but also include many more less familiar, but biologically important forms. This work covers the variety of ways in which both male and female gametes are produced by evolving different sexual systems in crustaceans, the range of reproductive systems, and the accordingly, and highly diverse, mechanistic modes of sex determination. In addition, the book features such topics as genetic and environmental determinants in sex determination pattern, variability of mechanisms of fertilization among different species, the origin of different mating systems, the associated mating and brooding behaviors, and the adaptive ability to different environmental conditions with discussion on the evolutionary ecology of social and sexual systems in certain species, which have shown eusocial tendencies, similar to social insects. Marine species occupying diversified ecological niches in tropical and temperate zones reproduce under definitive environmental conditions. Therefore, reproductive ecology of different crustaceans inhabiting different ecological niches also constitutes another important aspect of the work, along with yolk utilization and embryogenesis leading to release of different larval forms, which reflect on their aquatic adaptability. Forms a valuable source of recent references on the current research in crustacean reproductive physiology Covers various mating and breeding systems, providing illustrative examples for sexual selection, parental care of developing eggs and embryos, and the evolution of other reproductive behaviors Features contributions written in the form of review articles, enabling readers to not only gain information in the respective subject, but also help them stimulate ideas in their chosen field of research Includes a glossary created by the author to define technical terms Demonstrates the ability of crustacean species to serve as useful model systems for other organisms, to investigate issues related to sexual conflict, mate choice, and sperm competition Discusses techniques in endocrine research to help researchers in aquaculture develop protocols in the control of reproduction

Available in PDF, EPUB and Kindle. Book excerpt: During the vast stretches of early geologic time, the islands of the Caribbean archipelago separated from continental land masses, rose and sank many times, merged with and broke from other land masses, and then by the mid-Cenozoic period settled into the current pattern known today. By the time Native Americans arrived, the islands had developed complex, stable ecosystems. The actions these first colonists took on the landscape—timber clearing, cultivation, animal hunting and domestication, fishing and exploitation of reef species—affected fragile land and sea biotic communities in both beneficial and harmful ways. On Land and Sea examines the condition of biosystems on Caribbean islands at the time of colonization, human interactions with those systems through time, and the current state of biological resources in the West Indies. Drawing on a massive data set collected from long-term archaeological research, the study reconstructs past lifeways on these small tropical islands. The work presents a wide range of information, including types of fuel and construction timber used by inhabitants, cooking techniques for various shellfish, availability and use of medicinal and ritual plants, the effects on native plants and animals of cultivation and domestication, and diet and nutrition of native populations. The islands of the Caribbean basin continue to be actively excavated and studied in the quest to understand the earliest human inhabitants of the New World. This comprehensive work will ground current and future studies and will be valuable to archaeologists, anthropologists, botanists, ecologists, Caribbeanists, Latin American historians, and anyone studying similar island environments.

This book was released on 2014-06-05 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: This part B of the fourth volume of The Crustacea contains chapters on: ● Crustaceans in the Biosphere ● Crustaceans and Mankind ● Crustaceans in Art ● Orders Lophogastrida, Stygiomysida, and Mysida [collectively known as Mysidacea] As evident from the number 4B tagged to this volume, vol. 4 as originally planned had to be split into two fascicles, 4A and 4B, simply because of the numbers of pages covered by the various contributions meant for volume 4. The chapters in this book grew out of those in the French edition volumes 7(II) and 7(III)(A). Overall, this constitutes the seventh tome published in this English series, viz., preceded by volumes 1 (2004), 2 (2006), 9A (2010), 9B (2012), 3 (2012), and 4A (2013). Readers/users should note that from vol. 4A onward we have had to abandon publishing the chapters in the serial sequence as originally envisaged by the late Prof. J. Forest, because the various contributions, i.e., both the updates and the entirely new chapters, have become available in a more or less random order.

Available in PDF, EPUB and Kindle. Book excerpt: About 90 per cent of the 10,000 known species of the Crustacea Decapoda live in oceans and adjacent coastal and estuarine regions, and most of them pass through a complex life history comprising a benthic (juvenile-adult) and a planktonic (larval) phase. The larvae show a wide array of adaptations to the pelagic environment, including modifications in their functional morphology, anatomy, the molting cycle, nutrition, growth, chemical composition, metabolism, energy partitioning, ecology and behaviour.;All these traits are reviewed in this volume, attempting to promote an integrated, multidisciplinary view of the biology of larval Decapoda and other crustacean taxa. Emphasis is placed on the lesser-known anatomical, bioenergetic and ecophysiological aspects of larval life, as morphology has already been extensively documented. Changes in biological parameters (for example, rates of feeding, growth, metabolism) are shown in successive developmental stages, within individual stages, and as responses to environmental factors. Particular attention is paid to interrelationships between intrinsic phenomena (molting cycle, organogenesis, growth) and the overlaying effects of extrinsic factors (for example, food, temperature, salinity, pollution). Concluding from the available data, major bias and gaps in present knowledge of larval biology are identified and discussed as to their potential significance in future research.
