Diatoms are a group of unicellular algae, enclosed within a cell wall made of hydrated silicon dioxide and often featuring bilateral symmetry. They are major producers in the aquatic food chains of Earth, and as such are uniquely well-suited to provide support for larger organisms in your developing ecosystem.
- In real life, diatoms are often considered a class, a rank under phylum, although this is subject to some dispute.
