Cyclostrema is a term used in the field of zoology to refer to a genus of small, marine, and benthic gastropod mollusks belonging to the family Liotiidae. These mollusks are characterized by their unique spiral shell shape, which is typically rounded and disc-like, resembling a miniature cyclone or cyclotron, giving rise to the name "cyclostrema," which translates to "circular mouth" in Greek.
The shells of cyclostrema species are typically small in size, measuring only a few millimeters in diameter. Despite their diminutive stature, they possess intricate and ornate patterns, often displaying intricate, closely spaced ribbing or sculpture, which adds to their visual appeal.
These gastropods are primarily found in shallow coastal waters, specifically inhabiting intertidal zones and subtidal areas. Cyclostrema species can be found across various regions, including the Atlantic, Pacific, and Indian Oceans.
Due to their small size and elusive nature, cyclostrema gastropods often lead a secretive lifestyle, dwelling amongst marine vegetation, rocks, and crevices. They exhibit a strong attachment to their substrate, typically attaching themselves using a muscular foot while grazing on algae and detritus.
Overall, cyclostrema serves as an important genus within the field of zoology, helping researchers understand the diversity, ecology, and adaptations of small marine gastropods in various coastal ecosystems.
