Here are some key features of a great white shark's skin:
* Rough and sandpapery: The denticles create a rough, sandpapery texture that helps reduce drag in the water, making the shark more streamlined and efficient.
* Protective: The denticles act as a protective layer, shielding the shark from injuries caused by parasites, predators, and other external factors.
* Camouflage: The denticles help break up the shark's outline, making it harder for prey to spot them.
* Sensory: Some denticles contain receptors that sense vibrations and pressure changes in the water, providing the shark with a sense of touch and allowing it to detect prey.
Overall, the unique skin structure of great white sharks plays a critical role in their survival and success as apex predators.
