Fingerprint Patterns

Of all the MILLIONS of fingers in the world there are only 8 fingerprint patterns. There's the Plain Arch, Tented Arch, Ulnar Loop, Radial Loop, Double Loop Whorl, Plain Whorl, Central Pocket Whorl, and Acciddental Whorl. Of course some have multiple names but the pattern is the same. Anyways, here is a short list of each one's discription:

Plain Arch-a small hill that forms an almost perfect equalateral triangle
Tented Arch: a Plain Arch extended upwards
Ulnar Loop: curvy L figure
Radial Loop: backwards curvy L figure
Double Loop: two intwined whorls
Plain Whorl: multiple cricles placed in the center
Central Pocket Whorl: Combination of the Tented Arch and a Plain Whorl Accidental Whorl: uncentered whorl(s) that may not form a circle

There are also different types of finger prints. They are as follows:
Direct: pressed into a medium such as blood, dirt, or substance in which the print (visible to the naked eye)
Latent: usually made from leaving sweat or bobily fluids that in turn leave a print ( not visible with the naked eye)
Plastic: an indentation into wax, clay or pliable substance (visible to the naked eye)
