Evans; Neil Schlager and Jayne Weisblatt, editors Pronunciation Guide for Scientific Names Words to Know Getting to Know Crustaceans, Mollusks, Segmented Worms, and Their Relatives Clam worms, sand worms, and tubeworms Myzostomids Earthworms Leeches Beard worms Hydrothermal vent and cold seep worms Peanut worms Echiurans Velvet worms Water bears Remipedes Cephalocarids Fairy shrimps, tadpole shrimps, and clam shrimps and water fleas Leptostracans Mantis shrimps Bathynellaceans Anaspidaceans Krill Amphionids Crabs, shrimps, and lobsters Mysids Lophogastrids Cumaceans Tanaids Mictaceans Spelaeogriphaceans Thermosbaenaceans Pillbugs, slaters, and woodlice Amphipods Barnacles and relatives Grzimek’s Student Animal Life Resource: Crustaceans, Mollusks, and Segmented Worms offers readers comprehensive and easy-to-use information on Earth’s crustaceans, mollusks, and segmented worms. Entries are arranged by taxonomy. Each entry includes sections on physical characteristics; geographic range; habitat; diet; behavior and reproduction; animals and people; and conservation status. All entries are followed by one or more species accounts with the same information as well as a range map and photo or illustration for each species. Entries conclude with a list of books, periodicals, and Web sites that may be used for further research. ADDITIONAL FEATURES Grzimek’s Student Animal Life Resource: Crustaceans, Mollusks, and Segmented Worms includes a pronunciation guide for scientific names; a glossary; an overview of Segmented Worms, Crustaceans, Mollusks, and their relatives; a list of species in the volume by biome; a list of species by geographic range; and an index. The volume has 159 full-color maps, photos, and illustrations to enliven the text, and sidebars provide additional facts and related information. NOTE Grzimek’s Student Animal Life Resource: Crustaceans, Mollusks, and Segmented Worms has standardized information in the Conservation Status section. The World Conservation Union (IUCN) Red List provides the world’s most comprehensive inventory of the global conservation status of plants and animals. Using a set of criteria to evaluate extinction risk, the IUCN recognizes the following categories: Extinct, Extinct in the Wild, Critically Endangered, Endangered, Vulnerable, Conservation Dependent, Near Threatened, Least Concern, and Data Deficient. These terms are defined where they are used in the text, but for a complete explanation of each category, visit the IUCN web page at http://www.iucn.org/themes/ssc/redlists/RLcats2001booklet.html.
