The goblin shark's pectoral fins are located on either side of its body, behind the head and below the gills. The fins are large and broad, and they are capable of generating a lot of thrust. Each pectoral fin is controlled by a set of powerful muscles that allow the shark to flap its fins up and down.
When the goblin shark wants to move forward, it will flap its pectoral fins in a continuous, wave-like motion. This motion creates a force of propulsion that drives the shark through the water. The shark can also use its pectoral fins to steer, by tilting them in different directions.
In addition to its pectoral fins, the goblin shark also has a pair of dorsal fins and a pair of anal fins. These fins help to stabilize the shark's body and provide additional lift when it is swimming. The shark can also use its caudal fin, or tail fin, to generate additional thrust.
