Sea Slugs: some gastropods graze on algae and take up the photosynthetically active chloroplasts.

Lichens: partnerships between green microalgae (or cyanobacteria) and fungi, lichens are sensitive indicators of pollution and are a vital part of the arctic tundra.

Endosymbioses: the earliest marine organisms were green and red algae, formed as as a photosynthetic cyanobacterium was engulfed by another organism; other endosymbiotic exchanges led to the huge microalgal diversity.
