The Syndiniales are an
order of early branching
dinoflagellates (also known as Marine
Alveolates, "MALVs"), found as
parasites of
crustaceans,
fish,
algae,
cnidarians, and
protists (
ciliates,
radiolarians, other dinoflagellates).
[1]
[2]
[3] 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. Several MALV groups have been assigned to Syndiniales;
[4] recent studies, however, show
paraphyly of MALVs suggesting that only those groups that branch as sister to dinokaryotes ('core dinoflagellates') belong to Syndiniales.
