Diatoms (silicate algae) are single-celled, photosynthetic, eukaryotic organisms that inhabit a variety of aquatic and humid habitats. They can be found in a variety of habitats such as springs, streams, rivers, ponds, marshes, lakes, and marine ecosystems.
Wet habitats such as wet rocks, mosses, soil, and even caves are also common.
Their cell is covered with a silicate body (frustula) that has a specific shape and ornamentation.
According to the latest research from Pelister, 321 diatoms algae taxa have been registered. Of these, 16 taxons have morphological features different from the species previously known in the available taxonomic literature.
