Halichoerus grypus, commonly known as the grey seal, is native to the North Atlantic. It is characterized by its robust body, long snout, and spotted grey fur. Grey seals are known for their playful and inquisitive nature and often found basking on rocky shores or engaging in social behaviors in the water.

The grey seal (Halichoerus grypus) is native to the North Atlantic Ocean. Its geographical distribution includes both the eastern and western sides of the Atlantic. In the eastern Atlantic, grey seals are found along the coasts of the United Kingdom, Ireland, Norway, and the Baltic Sea. In the western Atlantic, they are primarily located along the coastlines of Canada and the northeastern United States, particularly in areas like Nova Scotia, Newfoundland, and the Gulf of Maine.

Grey seals inhabit coastal environments, including rocky shores, sandy beaches, and islands. They are often found in areas with temperate to subarctic climates. The species prefers regions with access to both land for breeding and open water for foraging. The environmental conditions typically range from cold to moderately cold waters, which are rich in marine life.

Grey seals occupy an ecological niche as apex predators in their marine environment. They primarily feed on a variety of fish and invertebrates, including sand eels, cod, and herring. They play a crucial role in their ecosystem by helping to regulate fish populations. Their adaptability to both rocky and sandy habitats allows them to thrive in diverse coastal ecosystems.
