The Grey Seal is a large marine mammal found primarily in the North Atlantic Ocean. They have a robust body, a broad head, and can weigh between 200 to 400 pounds. Their fur is typically gray with darker spots, which helps them blend into their rocky coastal habitats. Grey seals are known for their strong swimming abilities and can dive to depths of over 600 feet in search of fish and squid. They are social animals, often seen in large groups on beaches or rocky shores, where they haul out to rest and breed.
