nonmarine

Nonmarine describes organisms, environments, or geological formations that exist or originated outside of ocean or sea settings.

It encompasses freshwater, terrestrial, and brackish habitats—essentially anything that isn't saltwater marine.

The term appears most often in scientific contexts like paleontology and geology: nonmarine sediments, nonmarine fossils.

A nonmarine species might live in lakes, rivers, or on land, but not in the ocean.
