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] Paramecium aurelia demonstrate a strong “sex reaction” whereby groups of individuals will cluster together, and emerge in conjugant pairs. This pairing can last up to 12 hours, during which the micronucleus of each organism will be exchanged.[3] In Paramecium aurelia, a cryptic species complex was discovered by observation.[4] Since then, some have tried to decode this complex using genetic data.[5]
