There are three (3) subgroups of whorl fingerprints: That’s a total of eight print types. The types of fingerprint patterns are plain arch, tented arch, radial loop, ulnar loop, double loop, accidental whorl, plain whorl, and central pocket whorls.
Fingerprints begin forming during the 12th week of gestation, and barring surgical or accidental removal of the finger itself, will remain permanent for the life of the individual until the body. Ridge tracing in fingerprint is used to obtain the classification value for whorl by drawing an imaginary line from the extreme left to right delta and then counting the intermediate ridges. It is a special extension majorly used to classify the large groups of whorls patterns such as 32/32. A whorl fingerprints is that type of pattern in which at least two deltas are present with a recurve in front of each (figures 3.56 through 3.103).
