Anzoplana

Anzoplana is a genus of acoelomorph worms belonging to the family Isodiametridae. Acoelomorpha is a phylum of simple, bilaterally symmetrical, marine worms, lacking a through-gut (i.e., they possess a mouth but no anus). Anzoplana species are generally small, free-living, and found in marine benthic environments, typically in sandy or muddy substrates.

The genus Anzoplana is characterized by specific anatomical features related to their reproductive system and overall body plan. These characteristics are important for distinguishing them from other genera within the Isodiametridae family and the broader Acoelomorpha phylum. Scientific descriptions of Anzoplana include details regarding the arrangement of their statocyst, the structure of their frontal organ, and characteristics of their sperm and copulatory organs.

Research on Anzoplana, like other acoelomorphs, contributes to our understanding of early animal evolution and the origins of bilaterian body plans. Studies often involve morphological analysis, phylogenetic analyses using molecular data, and ecological investigations into their distribution and roles within marine ecosystems.
