A catch-all term for a wide variety of small aquatic organisms, plankton form the bedrock of many food chains in the oceans of Earth. Because of the wide variety of organisms within this category, plankton make for a very flexible starting place when designing a new organism.
- As the in-game description refers to, in real life plankton is not a taxonomic group, but rather includes all aquatic life that can't swim against a current. A species can be plankton only for the early stages of their lives and grow to be non-plankton fish, etc. While most are microscopic, some larger creatures like adult jellyfish can be plankton.
- The in-game icon resembles a copepod. While resembling shrimps, they are actually more closely related to barnacles.
