Both the leopard shark and zebra shark have revolutionized movement by utilizing their dorsal fins rather than relying on an anal fin. These remarkable creatures have adapted their bodies in unique ways, allowing them to navigate through the water with incredible agility.

The leopard shark, known for its distinctive spotted pattern, can grow up to 7 feet in length. What sets it apart from other sharks is the absence of an anal fin, which is typically used for stability and steering. Instead, the leopard shark relies on its dorsal fins, located along its back, to propel itself forward. These fins, known as the first and second dorsal fins, oscillate rapidly, creating a powerful propulsion force that allows the shark to swim effortlessly through the water.

The zebra shark, also known as the leopard shark (despite being a different species), exhibits a similar adaptation. With its long and sleek body, the zebra shark can reach lengths of up to 12 feet. Like the leopard shark, it lacks an anal fin but makes up for it with its prominent dorsal fins. The zebra shark’s first and second dorsal fins are elongated and flexible, allowing it to undulate its body in a wave-like motion. This unique movement pattern enables the zebra shark to gracefully maneuver through the water, making it a master of dorsal fin movement.
