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.
