Phylum Cycliophora is a unique group of animals that have only been discovered recently, making it a relatively new area of study. Some synonyms for this particular phylum include wheel animalcules and Cycliophoran worms. These names are derived from the circular feeding apparatus possessed by these organisms, which consists of a ring of ciliated tentacles that they use to capture food particles from the water. Other synonyms for Phylum Cycliophora include Loricifera, which refers to the protective armor or "lorica" that these animals possess, as well as Symbiontida, which highlights their ability to form close partnerships with other organisms. The study of Cycliophora is still in its early stages, and researchers continue to discover new aspects of these fascinating creatures.
