Jocelyn Crane presents a survey of the members of the genus Uca, with special reference to their morphology, social behavior, and evolution. Her account is firmly based on numerous field studies along the world's warmer shores and on comparative work in laboratories and museums. Originally published in 1975. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

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.

"A basic exploration of the appearance, behavior, and habitat of crabs, the widespread shelled crustaceans. Also included is a story from folklore explaining why crabs look as though they are headless"--

Every November, Christmas Island red crabs take over Christmas Island as millions march to the shores of the Indian Ocean. These crawling critters stop at nothing to reach their mating grounds. They halt traffic and even fall from cliffs! This title is filled with facts, maps, and fascinating graphics that take readers through the rain forest to the ocean with Christmas Island red crabs.

Hermit crabs have 10 legs and switch shells when they get too big for their current shell. The answers to many questions about hermit crabs are found in this bilingual book. English language learners discover how to take care of these fascinating pets through accessible text presented in both English and standard Latin American Spanish. Detailed photographs are presented alongside engaging and informative text in a way that makes learning about these pets educational and entertaining.

Simple text explaining what crabs look like, where they live, and what they like to eat will be alongside colorful full-bleed images. This title is complete with bolded glossary words, a picture glossary, and a Some Kinds of Crabs page, which will show a few different crab species. Aligned to Common Core Standards and correlated to state standards. Abdo Kids Junior is an imprint of Abdo Kids, a division of ABDO.

Learning marine biology from a textbook is one thing. But take readers to the bottom of the sea in a submarine to discover living fossils or to coral reefs to observe a day in the life of an octopus, and the sea and its splendors come into focus, in brilliant colors and with immediacy. In Sensuous Seas, Eugene Kaplan offers readers an irresistibly irreverent voyage to the world of sea creatures, with a look at their habitats, their beauty and, yes, even their sex lives. A marine biologist who has built fish farms in Africa and established a marine laboratory in Jamaica, Kaplan takes us to oceans across the world to experience the lives of their inhabitants, from the horribly grotesque to the exquisitely beautiful. In chapters with titles such as "Fiddler on the Root" (reproductive rituals of fiddler crabs) and "Size Does Count" (why barnacles have the largest penis, comparatively, in the animal kingdom), Kaplan ventures inside coral reefs to study mating parrotfish; dives 740 feet in a submarine to find living fossils; explains what results from swallowing a piece of living octopus tentacle; and describes a shark attack on a friend. The book is a sensuous blend of sparkling prose and 150 beautiful illustrations that clarify the science. Each chapter opens with an exciting personal anecdote that leads into the scientific exploration of a distinct inhabitant of the sea world--allowing the reader to experience firsthand the incredible complexity of sea life. A one-of-a-kind memoir that unfolds in remarkable reaches of ocean few of us can ever visit for ourselves, Sensuous Seas brings the underwater world back to living room and classroom alike. Readers will be surprised at how much marine biology they have learned while being amused.

The numerous species of Sand Crabs that roam our beaches are fascinating little creatures. Their tall eyes are perched high on top of slender stalks. They are like nature's tiny periscopes, allowing them to peer safely out of their holes. Sand Crabs are a joy to watch. They scurry about at speeds close to 15 feet per second back and forth from their burrows and then peek out to see if it is safe to come out again. Stalk Eyes is the story of a special Fiddler Crab with exceptionally tall eyes. With its cast of endearing characters, endless humor, and playful illustrations, Stalk Eyes captures the importance of being kind to others. After being teased at school for being different, Stalk Eyes uses his exceptionality to save the lives of his classmates. It's true-heroes do come in all shapes and sizes as shown by this special Fiddler Crab! Let's join together to embrace the importance of individual acceptance. Be kind to everyone around you. They could someday become your hero, too.
