El pinípedo de distribución más amplia, la foca común (Phoca vitulina) habita las costas templadas y subárticas del Atlántico Norte y el Pacífico Norte. Los adultos alcanzan hasta 130 kg y pasan aproximadamente el mismo tiempo en el mar cazando peces, calamares y crustáceos que descansando en playas y rocas. Sus grandes y expresivos ojos están adaptados para la visión subacuática en condiciones de poca luz. La foca común es una fuente de alimento fundamental para orcas, tiburones y osos polares.
