Grey Seal Strikes a Pose

A Grey Seal (Halichoerus grypus) poses in the waters off Acadia National Park in Maine. Grey seals live on both coasts of the Northern Atlantic, with breeding colonies in Great Britain, Ireland, and down the eastern coast of North America from Canada down to New Jersey.

They used to be hunted in the United States, but their numbers have grown since the passing of the US Marine Mammal Protection Act in 1972.
