== Sharkskin ==
Sharkskin refers to the unique texture and structure of the skin of sharks, a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Sharkskin is notable for its rough texture, which is due to the presence of tiny, tooth-like structures called dermal denticles or placoid scales.
Structure
Sharkskin is covered with dermal denticles, which are small, tooth-like structures that reduce drag and turbulence, allowing sharks to swim more efficiently. These denticles are made of dentin, similar to human teeth, and are covered with a hard enamel-like substance. The unique arrangement and structure of these denticles give sharkskin its hydrodynamic properties.
Function
The primary function of sharkskin is to reduce drag and increase swimming efficiency. The rough texture of the skin helps to minimize the formation of turbulent eddies, which can slow the shark down. Additionally, the dermal denticles provide protection against parasites and injuries.
Applications
The unique properties of sharkskin have inspired various technological applications. For example, sharkskin-inspired materials are used in swimsuits to reduce drag and improve performance. Additionally, sharkskin-like surfaces are being developed for use in aerospace and marine engineering to reduce drag and improve fuel efficiency.
Related Species
Sharkskin is found in all species of sharks, including the great white shark, hammerhead shark, and tiger shark. Each species has variations in the size and shape of the dermal denticles, which can affect their swimming efficiency and behavior.
