Ammodytes, commonly known as sand eels, are small fish found primarily in the North Atlantic Ocean. They inhabit sandy coastal areas and are known for their elongated bodies and pointed snouts. These fish play a crucial role in the marine ecosystem, serving as a significant food source for various predators, including seabirds and larger fish. Sand eels are typically around 15 to 30 centimeters long and are characterized by their silver sides and dark backs. They are often found buried in the sand, which helps them avoid predators. Ammodytes are also important for commercial fishing, as they are used as bait and in the production of fishmeal.
