An Annotated Checklist Of The Marine Macroinvertebrates Of Alaska

A current and comprehensive species list of marine invertebrates of Alaska is essential for effective management of living marine resources, sustainable fisheries, conservation of vulnerable ecosystems, and advancement of our knowledge of biodiversity and ecosystem function. Furthermore, the most current checklist available to resource managers and scientists is quite dated and limited in that it only includes the marine invertebrates of the southern coast of Alaska to California. Since that checklist was published, many new species have been described, many range extensions have been discovered, and considerable changes in higher-level systematics have been made. The checklist that we have compiled lists 3708 species and presents for each species the currently accepted scientific name and its significant synonyms, common names, type localities, geographic and depth distributions, a general statement of abundance in Alaska when known (e.g., rare, uncommon, common, abundant), and general remarks. It includes species recorded in the marine waters of Alaska from the intertidal zone, continental shelf, and upper continental slope to abyssal depths, from the Beaufort Sea at the Arctic border with Yukon, Canada; the eastern Chukchi Sea, the eastern Bering Sea, the Aleutian Islands to the western border with Russia; and the Gulf of Alaska to Dixon Entrance at the southern border with British Columbia. Sound and reliable taxonomic identifications are necessary to monitor and predict changes in the distribution and abundance of marine species. The current status and future direction of the study of Alaskan marine invertebrate biodiversity are briefly discussed.

Approximately 6500 non-endoparasitic species are listed from the region bound by Point Conception, California to the south, and Kodiak Island, Alaska to the north and west; and seaward approximately 200 miles.

This is the largest species of sea pen encountered by divers in the northern Pacific. the short, slender branches of the stalk are white, as are the polyps.

In this expanded and revised edition of Sea Stars of British Columbia, originally published in 1981, Philip Lambert describes 43 species and subspecies of sea stars in the coastal waters of northwestern North America. Lambert has expanded the geographic area to include the region from Glacier Bay in southeastern Alaska to the waters of Juan de Fuca Strait and Puget Sound of northern Washington. The sea star fauna of this region is the most diverse of all the temperate waters of the world. The great age of the Pacific Basin, and the varied habitats along this complex coastline, created by scouring glaciers and other natural forces, have stimulated the evolution of many new forms. Although he covers the coastal waters down to 200 metres below the surface, Lambert lists 26 more species that live below 200 metres and 14 others that occur just outside the region covered by this book.
