mesozooisella

Mesozooisella is a genus of microscopic, single-celled organisms belonging to the phylum Ciliophora. These ciliates are characterized by their oval to elongated shape and are typically found in marine and brackish water environments, often associated with sediment or organic detritus. A key distinguishing feature of Mesozooisella is the presence of a distinct buccal cavity, which is the entrance to their oral apparatus used for ingesting food particles. Their movement is facilitated by cilia, short hair-like appendages that cover their body surface. Reproduction in Mesozooisella, as with other ciliates, occurs primarily through asexual binary fission. The genus was first described in the early 20th century, and research has focused on its morphology, ecological role as a consumer of bacteria and smaller plankton, and its distribution in various aquatic ecosystems. Further taxonomic and phylogenetic studies continue to refine our understanding of its place within the ciliate tree of life.
