Noctiluca scintillans, the sea sparkle. Dinoflagellates are usually photosynthetic. Although it is capable of performing photosynthesis this large dinoflagellate has a different lifestyle. It uses an adhesive tentacle to seize prey. It may also feed on small food particles using a net of fine mucous threads.
