The acronym SEAL in the United States Navy SEALs stands for Sea, Air, and Land. It is derived from the teams' ability to operate on the seas, in the air, and on land.
For the common seal of a company, see company seal. The harbor (or harbour) seal (Phoca vitulina), also known as the common seal, is a true seal found along temperate and Arctic marine coastlines of the Northern Hemisphere.
