Pectoral Fin

Real World Example

Imagine trying to carry a heavy grocery bag while keeping it close to your body to maintain balance and avoid straining your arms. The way you strategically hold the bag with your arms tucked close resembles how a fish uses its pectoral fins, which are located on each side and usually kept folded just behind their operculum. Just as your arms help stabilize and maneuver the load while being close to your torso, a fish's pectoral fins assist in balancing and steering through water, providing stability and control in their aquatic environment.
