Publisher's Synopsis
With today's concern over the pollution of our coastlines in the Nothern Hemisphere, there is an ever greater need for a watchful public eye over the marine life of our shores. Oil spills, toxic drainage and radical disturbances to the ecology are putting a strain on the vast populations of molluscan seashells of all temperate seas.;This guide with its global perspective covers the Eastern Pacific (from the Aleutians to Oregan), the Western Atlantic (from Labrador to Virginia), and the Eastern Atlantic (from Norway to Portugal). Nearly 400 species of common bivavles and univalves are illustrated with proper scientific and common names, clear descriptions, ranges and habitats. Many of these species are circumpolar, some ranging from Siberia to Greenland, and others from Finland to Alaska.;In addition, there are clear instructions on how to observe, make a census, and collect samples of shells, as well as basic data on molluscan shell parts, ecology, and the care of shell collections.
