The common seal lives in cold and temperate seas of the northern hemisphere. It is a medium-sized seal with a short muzzle and spotted fur, which swims and dives well.
The common seal differs from other seals in its short muzzle and spotted coloration. It is important for marine nature because it helps control fish populations and serves as food for orcas and polar bears.
