How does the torpedo-shaped body of a white shark help it swim?

The white shark possesses a body shaped like a blunt torpedo, a streamlined form that facilitates movement through the water. While this shape is characteristic of the species, some scientific discussion suggests that a bulky body plan may present more resistance than a sleeker, more slender body shape when moving through the water.12

To support its active hunting lifestyle, the white shark relies on more than just its shape; it is equipped with powerful muscles and a specialized circulatory system. This system enables regional endothermy, an adaptation that conserves heat generated by muscle contractions. By warming critical regions of its body above the temperature of the surrounding water, the shark can remain active and efficient in environments that might otherwise be too cold for other predatory fish.12
