Harbor Seal
The Harbor Seal, also known as the Common Seal, is a marine mammal native to the coastal waters of the Northern Hemisphere. It is known for its dog-like face and its sleek, streamlined body.
Harbor Seals are highly social animals that live in large colonies. They are a vital part of the marine ecosystem, as their presence helps to control the populations of their prey, including fish and squid.
