Rhogostoma minus is a species of thecate amoeba that belongs to the phylum Cercozoa. It was first described by Belar in 1921.[1] These amoebae are heterotrophic, which means that they consume other organisms for nutrition. The cells of Rhogostoma minus are typically between 8 and 12 μm in diameter and are surrounded by a protective organic covering called a theca.[2] The theca has a unique cleft-like opening that allows the amoebae to extend and retract thread-like projections called filose pseudopodia.[3] The amoebae move along surfaces by pulling themselves forward using their pseudopodia.

Rhogostoma minus can be found in various environments, including freshwater, soil, and wastewater.[4] In fact, researchers have discovered that Rhogostoma minus forms an endosymbiotic relationship with certain bacteria called Gammaproteobacteria, which belong to the order Legionellales, in wastewater treatment plants.[5]
