Diatom with strongly developed internal intrusions of the frustule, girdle view.

Empty frustules by phase contrast microscopy. Generic identity needs to be confirmed.

Its the thing on the left (the thing on the right is a sand grain). A rather asymmetrical and often twisted pennate diatom, which in this case has valves that are a bit dish-like and are very often twisted. Frustule only, differential interference contrast optics.
