Gray seals are large marine mammals found along the coasts of the North Atlantic Ocean. They have a distinctive grayish coat with dark spots and can weigh between 400 to 800 pounds. Gray seals are known for their playful behavior and can often be seen basking on rocky shores or swimming in the ocean. These seals primarily feed on fish and invertebrates, using their keen eyesight and whiskers to locate prey. They are social animals, often found in groups, and are known to dive to depths of over 600 feet while hunting. Gray seals are an important part of the marine ecosystem and are protected in many areas.
