The Syndiniales are an order of dinoflagellates, found exclusively as endosymbionts of the tintinnid ciliates, crustaceans, fish, protozoa, algae, and other dinoflagellates.[1] The trophic form is often multinucleate, and ultimately divides to form motile spores, which have two flagella in typical dinoflagellate arrangement. They lack a theca and chloroplasts, and unlike all other orders, the nucleus is never a dinokaryon. A well-studied example is Amoebophrya, which is a parasite of other dinoflagellates and may play a part in ending red tides.

The order Syndiniales belongs to the class Syndiniophyceae or Syndinea.[2]
