Species of Paramecium range in size from 0.06 mm to 0.3 mm in length. Cells are typically ovoid, elongate, or foot- or cigar-shaped. The body of the cell is enclosed by a stiff but elastic structure called the pellicle.
Paramecium caudatum [1] is a species of unicellular protist in the phylum Ciliophora. [2] They can reach 0.33 mm in length and are covered with minute hair-like organelles called cilia. [3] The cilia are used in locomotion and feeding. [2] The species is very common, and widespread in marine, brackish and freshwater environments. [4] [5]

Paramecium biaurelia is a unicellular protist with elongated body, which measures about 133 μm in length. The distinguishing feature from other species of P. aurelia is that it reproduces at below 21°C and specifically between 9 PM and 7 AM. [ 10 ]

The length of Paramecium sonneborni is between 130 and 186 μm with a mean length of 154μm. [1] It is the newest member of the Paramecium aurelia species complex. The current Paramecium sonneborni strains, so far, reveal very low viability in the generations and are a result of allopatric speciation.
Paramecium aurelia [1] are unicellular organisms belonging to the genus Paramecium of the phylum Ciliophora. [2] They are covered in cilia which help in movement and feeding. [ 2 ] Paramecium can reproduce sexually , asexually , or by the process of endomixis . [ 3 ]
The Aeolosomatidae is a family of very small, aquatic annelid worms, between 0.3 and 10 mm in length and 0.04-0.06 mm in diameter. About 30 species have been described in three genera . [ 2 ] These worms are known as suction-feeding worms and occupy freshwater, brackish, and saltwater habitats.
