fins
Each species of fish has unique uses for their fins, but simply put fish use their fins to propel and to steer themselves.
Fish use fins to help them swim better. If you go swimming, you will swim faster, with swim fins, instead of just feet. Fins are better for fish instead of hands.
A fish uses its fins for steering, balance, and movement in water. Fins help the fish to navigate, change direction, and maintain stability while swimming through the water.
