Underwater-turn around
Shark movement is much like an airplane, they use their caudal fin (tail) for forward movement, and the pectoral fins to maintain their horizontal position in the water. Their pectoral fins, on either side of their bodies, can be angled differently, changing the path of water moving around them, much like the wings of an airplane. These fins also control up and down movement in the water column. The dorsal fin works as a stabilizer and can also be bent from left to right which assists with sharp turns. Great white sharks also have a pelvic fin, an anal fin and a tiny second dorsal fin. All this fins and their arrangement give white sharks amazing maneuverability in the water, allows them to reach great speeds, stop suddenly and make sharp turns in all directions. This image, taken from a research vessel in Gaansbaai in 2010 captures a Great white shark making a sharp turn to its left away from the vessel while smiling at the camera.
