A hair whorl is a patch of hair growing in the opposite direction of the rest of the hair. Hair whorls occur in most hairy animals, on the body as well as on the head. Hair whorls, also known as crowns, swirls, trichoglyphs, or cowlicks, can be either clockwise or counterclockwise in direction of growth. Hair whorls on the head parietal whorls have been studied by some behaviorists. Most people have clockwise scalp hair whorls. Parietal whorls which are considered to be normal scalp patterns could be a single whorl or double whorls. Cases of triple parietal whorls are less common but do not necessarily indicate abnormality. Citation needed date December 2008 Amar J. Klar conducted research to see if there was a genetic link between handedness and hair whorl direction. He found that 8.4 of right handed people and 45 of left handed people have counterclockwise hair whorls. His research indicates that a single gene may control both handedness and hair whorl direction. ref name KlarAJ Human handedness and scalp hair whorl direction develop from a common genetic mechanism.

In biology, a whorl might occur at the ends of different structures or occur in the middle of structures. It s often used to describe the structures of organs and used in the aid of identification. It s a cluster of cells or tissue that surround another, that starts at the same plain of axis or starts at one point and wraps around that point in an expanding circular pattern.

Hair whorls in horses are found on various parts of the body. A hair whorl is a patch of hair growing in the opposite direction of the rest of the hair. Hair whorl s can occur on animals with hairy coats, and are often found on horse s and cow s. Locations where whorls are found in equines include the stomach area, the face, stifle areas, and sometimes on the hocks. Hair whorls in horses are also known as crowns, swirls, trichoglyphs, or cowlicks and can be either clockwise or counterclockwise in direction of growth.

The genus name from which this subfamily name is taken is derived from the Greek plesios , near, in the sense of plesiomorphic, of characteres near the ancestor, combined with Cystiscus the name of another closely related genus. Sometimes the genus in this subfamily is more simply left in the larger family Marginellidae . Note Gastropod taxonomy has been in flux for more than half a century, and this is especially true currently, because of new research in molecular phylogeny .
