KIRKUS REVIEW

 Not true crabs but arthropods, the 9,000,000 armor-plated horseshoe crabs in waters from New York to North Carolina are little changed from their ancestors of 500 million years ago. Once considered a nuisance by fishermen who harvested as many as 4 million a year and ground them for fertilizer, the species is gaining the respect of scientists studying its unusual blood, brain, eyes, and armor plating. The blood is used in cancer research and in testing for the presence of bacteria and toxins; chitin from the shell promotes healing. In this entry in the ``Remarkable Animals'' series, Day (who once worked in a crab-blood processing plant) notes current efforts to protect and celebrate the horseshoe crab; she includes photos of the First Annual Horseshoe Crab Festival (in New Jersey in 1991), and concludes with information on an Adopt-a-Crab Club and sources of live and preserved crabs. Though some of the color photos are muddy or dark, others are excellent--a close-up of the compound eye, for example, or embryos in their fluid-filled sacks. A wealth of information in attractive format. Brief fact summary; glossary; index. (Nonfiction. 9-12)
