How do weedy sea dragons swim?

Weedy sea dragons swim by using their dorsal fins, which are located on their backs. These fins are small and nearly transparent, allowing for subtle and precise movements. Unlike many fish, they do not use their pectoral fins for propulsion; instead, they rely on their elongated bodies and the movement of their dorsal fin to navigate through the water, often utilizing their unique body shape to blend in with surrounding seagrass and kelp for camouflage.
