PROTOZOA


BIOLOGY
TAXONOMY OF KINGDOM ANIMALIA
PHYLUM: PROTOZOA
paramesium
The phylum Ciliophora includes the family Paramecidae, the Paramecium. Like the other members of the phylum, Paramecium is a ciliated single celled creature. Species of Paramecium can be distinguished from other ciliates by their cigar or slipper shape and the undulating membrane within the peristome - a furrow that leads to the cytostome, where food vacuoles are formed. Most Paramecium are large as protists go, on the order of 0.5 mm long by perhaps 1/3 as wide.
