Description and Significance

Noctiluca scintillans, also known as sea sparkles, are single celled dinoflagellates that range between 200-2000 micrometers in diameter. They are free living, marine plankton that are mostly found in estuaries and other coastal regions and can be found in both warm and cold waters. N. Scintillans are heterotrophic and non-photosynthetic, meaning they receive their carbon from organic compounds and receive energy through the ingestion of organic substances. Noctiluca scintillans are non-motile, even though they possess a flagellum, and only move vertically by changing their buoyancy using gas vacuoles. N. Scintillans can reproduce asexually, by binary fission, and sexually, using isogametes through a diplontic lifecycle.
