Shark skin

Definition

Shark skin refers to the unique dermal structure found on sharks, characterized by tiny, tooth-like scales called dermal denticles. These denticles create a rough surface that minimizes drag and turbulence in water, offering the shark hydrodynamic advantages. This natural design has inspired bioinspired surface modifications in various materials to enhance performance and functionality, showcasing the potential of biomimetic materials in industrial applications.
