WHITE-SIDED DOLPHIN (Lagenorhynchus acutus): Western North Atlantic Stock
White-sided dolphins are found in temperate and sub-polar waters of the North Atlantic, primarily on continental shelf waters to the 100 m depth contour. The species inhabits waters from central we st Greenland to North Carolina (about 35°N) and perhaps as far east as 43 o W (Evans 1987). Distributi...
