Whorl

A whorl is a fingerprint pattern characterized by circular or spiral ridges that form a complete or partial loop. These patterns typically have two deltas (triangular ridge points) and a core (central feature). Whorls are common and come in various types, such as plain, central pocket, double loop, and accidental. They are unique to each individual, making them valuable for biometric identification. Think of them as swirling ridge patterns that resemble ripples in water—distinctive and identifiable for forensic and security purposes.
