What is the difference between fins and wings?

Fins and wings are both appendages used for movement, but they serve different functions and are found in different species. Fins, typically found in aquatic animals like fish, are flat structures that help with propulsion, steering, and stability in water. Wings, on the other hand, are primarily associated with birds and insects and are designed for flight, allowing these animals to generate lift and navigate through the air. While both structures are adaptations for movement, their design and function are tailored to their specific environments.
