Sea stars (Echinodermata: Asteroidea) of arctic North America / by E.H. Grainger. : Fs94-152E-PDF

"Twenty-four species of sea stars are reported from northern North American waters between the Strait of Belle Isle and Point Barrow, Alaska. A key for identification and morphological descriptions of all the recorded species and several of probable occurrence in the region are included. Data are given on geographical distribution and on depth, substrate, temperature, and salinity conditions. Arctic subarctic waters surrounding the Arctic Ocean are shown on the basis or sea star distribution to comprise two major zoogeographical regions: Atlantic-arctic andPacific. Arctic North America east of about 1200W is included in the Atlantic arctic region. Farther west the fauna is primarily Pacific."--Abstract.
