A single Biddulphia diatom frustule, rendered in precise girdle view. The specimen features a characteristic box-shaped silhouette with two prominent spines projecting from opposite corners. The delicate shell walls are depicted as a light, open grid of rectangular pores. This scientific illustration captures the exact geometry of microscopic marine silica. The clean line art style presents the structure without shadow or secondary elements.
