Dinoflagellates are single-celled organisms. They get their name from the two hair-like flagella that they can use for swimming. Dinoflagellates can be photosynthetic but many species get part or all of their energy from ingesting other organisms or detritus, like the exceptionally large sea sparkle Noctiluca scintillans.
