Harbor seals are found along the Pacific coast of North America, from the Pribilof Islands to Baja California, Mexico. Harbor seals generate a greater amount of body heat than comparable land mammals due to their higher metabolic rate. Their thick layer of blubber prevents heat loss, and can be drawn upon for energy as well. LeConte Glacier, Alaska
