How do ciliates differ from other protozoans?
Zooflagellates differ from other protozoans because they are unicellular and may live on their own or on a host as a parasite. They have long bodies with one large nucleus. They reproduce by binary fission.
How many known species of protozoans are there?
There are approximately 30,000 known species of protozoans.
What are the four Phyla of Protozoans?
The four Phyla of Protozoans are Sarcomastigophora, Apicomplexa, Ciliophora, and Microspora.
What are protozoans that cannot move called?

Sponge

What are habitat of poriferans and coelentrates?
All poriferans and coelenterates live in water, most of them in sea water, but some in fresh water. Poriferans are bottom-dwellers. Coelenterates can be free-swimming, fixed to the bottom or live in colonies fixed to the bottom, depending on species and face of life.
Are all protozoans prokaryotic and autorophic?
No, not all protozoans are prokaryotic and autotrophic. Protozoans are eukaryotic organisms that can be autotrophic or heterotrophic. Autotrophic protozoans can photosynthesize like plants, while heterotrophic protozoans rely on organic matter for nutrition.
Are protozoans are unicellular or multicellular?
protozoans are unicellular organisms
Do protozoans have skeleton?
No Protozoans do not have skeleton. They are unicellular organisms.
Do poriferas have brains?
No, poriferans do not have brains or any other organs.
