Paramecium caudatum

Macronuclear inclusion body
|  Genus: Cigar- or foot-shaped; a single macronucleus and 1 to several vesicular or compact micronuclei 
(Kudo, 1966). Species: 180-300 μm long; 
a compact micronucleus; two contractile vacuoles (Kudo, 1966).  
Cylindrical or cigar-shaped; rounded anteriorly, pointed posteriorly; one large compact micronucleus ("caudatum" group) 
approximately 8 μm diam.; two contractile vacuoles; 
170-290 μm long (Wichterman, 1986).  
Elongate, rounded anteriorly, pointed posteriorly; caudal cilia present; 
180-280 μm long; 
a single macronucleus with a single micronucleus; two contractile vacuoles (Carey, 1992).
