More seals arrived, clumsily using those naked flippers to haul themselves out onto the rocks of a jetty. Harbor Seals, Phoca vitulina literally means sea dog or sea calf, because their whiskered snouts look a little like that of a dog. Seals are members of the Pinniped family, which means “flippered feet.” The seals used these feet to pull themselves along on the rocks. Once they were out of the water, they extended those back flippers up, I’m assuming for both balance and thermoregulation.
