O pinípede de distribuição mais ampla, a foca-comum (Phoca vitulina) habita as costas temperadas e subárticas do Atlântico Norte e do Pacífico Norte. Os adultos atingem até 130 kg e passam tempo aproximadamente igual no mar caçando peixes, lulas e crustáceos e descansando em praias ou rochas. Seus grandes e expressivos olhos são adaptados para a visão subaquática em pouca luz. A foca-comum é uma fonte de alimento fundamental para orcas, tubarões e ursos-polares.
