Phoca vitulina is a scientific name for the harbor seal, a mammal that is commonly found along the coastlines of the Northern Atlantic and Pacific Oceans. Synonyms for this species include the following: common seal, hair seal, Spotted seal, Baltic seal, and Largha seal. These seals are known for their thick fur coats, which provide excellent insulation in chilly waters. They are social creatures and can be seen in groups of up to several hundred individuals. Due to habitat loss and human activity, harbor seal populations are declining in some areas, making conservation efforts essential for their survival.
