_Description._--The Steller sea lion resembles the California sea lion but is larger. Old bulls are from 10 to 12 feet in length and weigh from 1,200 to 1,500 pounds, perhaps even a ton. Females are 8 to 9 feet in length and may weigh up to 1000 pounds. The female Steller sea lion is nearly as large as the male of the California sea lion. The bull Steller sea lion lacks the high forehead characteristic of the California sea lion, and the body is heavier and stouter, especially in the neck and chest. Bulls are distinctly bicolored, the head, neck and chest being cinnamon and the rest of the body darker. Females are a uniform dark brown color. The Steller sea lion makes a loud, deep roaring sound. Steller sea lions occur along the coast of Asia south to Japan and the coast of North America from the Bering Strait south to central California. The range thus meets and overlaps that of the California sea lion. Steller sea lions are splendid swimmers and spend much of their time in the surf. They often lie in the water a few yards from where the waves pound some jagged cliff, retaining their dangerous position without discernible effort. They are curious and will raise their head and neck vertically out of the water to observe a passing boat. Much time is spent beneath the surface, presumably hunting fish. They sometimes leap up out of the water in an arching dive or may simply lower their heads beneath the surface and appear several minutes later at another place. They may come to the surface with a porpoiselike roll, breathe, and again dive. Many of their actions seem inspired by playfulness--a means of working off excess energy. Sea lions haul out on a number of rocky islands along the coast. They are slow and clumsy on land. Their rear flippers can be directed forward and so give them some assistance in moving about. When startled they are able, with much struggling, to move with fair speed to the water. They can dive from considerable heights.
