If you have trypophobia, consider not clicking the link.
"Trypophobia is a claimed pathological fear of holes, particularly irregular patterns of holes. ... Shapes that elicit a reaction were said to include clustered holes in innocuous contexts such as fruit and bubbles, and in contexts associated with danger, such as holes made by insects and holes in wounds and diseased tissue."
From https://en.wikipedia.org/wiki/Trypophobia, which contains a picture of a lotus seed head.
