<p><span class="taxon"><em>Somniosus microcephalus</em></span> live mainly on continental and insular shelves. They occupy intertidal regions in addition to some river mouths and shallow bay areas during the winter months and often move to depths from 180 to 550 meters during warmer months. They have been observed as low as 1200 meters, with one observation at 2200 meters off the coast of Georgia - extending its range both geographically and in terms of depth. In northern parts of their range, Greenland sharks are found from 0 to 1200 meters in waters from 1 to 12 degrees Celsius. In southern parts of their range, these sharks may occur at greater depths.<span> (Compagno and Fowler, 2005; Compagno, 1984)</span></p> <p><strong>Habitat Regions: </strong>Temperate; Polar; Saltwater or marine</p><p><strong>Aquatic Biomes: </strong>Pelagic; Coastal</p><p><strong>Other Habitat Features: </strong>Estuarine; Intertidal or littoral</p>
