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.
Tall green grass. Subtle melodies of songbirds. Sharp whines of muskrats. Rustles of water running through the grasses. And at low tide, a pungent reminder of the treasures hidden beneath the surface.All are vital signs of the great salt marshes' natural resources. Now championed as critical habitats for plants, animals, and people because of the environmental service and protection they provide, these ecological wonders were once considered unproductive wastelands, home solely to mosquitoes and toxic waste, and mistreated for centuries by the human population. Exploring the fascinating biodiversity of these boggy wetlands, Salt Marshes offers readers a wealth of essential information about a variety of plants, fish, and animals, the importance of these habitats, consequences of human neglect and thoughtless development, and insight into how these wetlands recover. Judith S. Weis and Carol A. Butler shed ample light on the human impact, including chapters on physical and biological alterations, pollution, and remediation and recovery programs. In addition to a national and global perspective, the authors place special emphasis on coastal wetlands in the Atlantic and Gulf regions, as well as the San Francisco Bay Area, calling attention to their historical and economic legacies. Written in clear, easy-to-read language, Salt Marshes proves that the battles for preservation and conservation must continue, because threats to salt marshes ebb and flow like the water that runs through them.
Updated to reflect recent research, the second edition of Marine Pollution discusses the sources of marine pollutants, their effects on marine organisms and humans, and how to reduce or eliminate them. Weis covers topics like oil spills, flame retardants, pharmaceuticals, noise pollution, and PFAS. A new chapter examines the prevalence of microplastics, how they find their way into our food, and the associated toxic chemicals. Additional chapters address the deadly effects of climate change in the ocean but also focus on actions that all people can take, citing recent environmental improvements as a cause for hope.

Synthesizing decades of work, but up-to-date, this book focuses on organism-level responses to pollutants by marine animals, mainly crustaceans, molluscs, and fishes. Emphasizing effects on physiological processes (feeding/digestion, respiration, osmoregulation), life-cycle (reproduction [including endocrine disruption], embryo development, larval development, developmental processes later in life (growth, regeneration, molting, calcification, cancer), and behaviour, the book also covers bioaccumulation and detoxification of contaminants, and the development of tolerance. The major pollutants covered are metals, organic compounds (oil, pesticides, industrial chemicals), nutrients and hypoxia, contaminants of emerging concern, and ocean acidification. Some attention is also devoted to marine debris and noise pollution.
