Optical Properties

These are consistent with the typical optical characteristics observed in the genus Varolia.

Remarks

The holococcolith features a crystalline-high wall with a modified square or rectangular shape, depending on the degree of tilting around the central void area. Typically, one side of the wall is more convex than the others, creating an asymmetrical appearance.
