Trypophobia is an aversion to the sight of irregular patterns or clusters of small holes or bumps. It is not officially recognized as a mental disorder, but may be diagnosed as a specific phobia if excessive fear and distress occur. Most affected people mainly experience disgust but not fear when they see trypophobic imagery.
It looks infested by something unpleasant. My pet theory is that revulsion was an evolutionary mechanism to discourage eating diseased or parasite-infested food (parallel to odors indicating organic putrification).
