Eels that live in the sand at beaches are typically species like the sand eel or the surf eel, which inhabit shallow coastal waters. These eels often burrow into the sandy substrate to hide from predators and ambush prey, feeding on small fish and invertebrates. Their elongated bodies and smooth skin allow them to navigate easily through the sand. They play an important role in the marine ecosystem by contributing to nutrient cycling and serving as prey for larger fish and birds.
