protist (/ˈproʊtɪst/ PROH-tist) or
protoctist is any
eukaryotic organism that is not an animal, plant, or fungus.
Protists do not form a
natural group...
- are no
longer classified together in one group. The best
known amoeboid protists are
Chaos carolinense and
Amoeba proteus, both of
which have been widely...

Marine protists Marine protists are
defined by
their habitat as
protists that live in
marine environments, that is, in the sal****er of seas or oceans...

Protozoa as a

Others class any
unicellular eukaryotic microorganism as
Protists, and make no
reference to 'Protozoa'...
- Coccolithop**** s**** Many
protists have
protective s**** or tests,
usually made from
silica (gl****) or
calcium carbonate (chalk).
Protists are a

amoeba or amoeboids.
Other protists are not motile, and
consequently have no built-in
movement mechanism.
Unicellular protists comprise a vast, diverse...
- antiprotozoal, the two
terms are confused, when in fact
protists are a supercategory. Therefore,
there are
protists that are not protozoans.
Beyond "animal-like"...
- This
means that it is
difficult to
define protists due to
their extreme differences and uniqueness.
Protists are a
polyphyletic [(of a

earliest eukaryotes were
likely protists.
Mating and ****ual

Unicellular eukaryotes are
