Spirotrichonymphids are a family of marine gastropod mollusks known for their unique, spiral-shaped bodies and ability to grow up to five times their original size. These mollusks belong to the order Gymnophora, which includes more than 30 genera.
Gymnophora is a group of marine benthic invertebrates characterized by their elongated, flattened bodies and the presence of four pairs of large, flexible muscles called pterygoids or gills. They are found mainly in warm tropical waters around the world. Gymnophora play an essential role in nutrient cycling through their ability to extract oxygen from water via specialized gas exchange mechanisms.
