Cestum Veneris is the scientific name for a type of ribbon-like marine creature, also known as the Venus girdle. Synonyms for Cestum Veneris can include sea belt, ribbon jellyfish, and comb jelly. These creatures typically have a transparent, ribbon-like body with ciliated comb-like rows that help them move through the water. They are found in most oceans around the world and are a popular subject for marine biologists. Despite their jellyfish-like appearance, they are actually part of the ctenophore family, a diverse group of animals often referred to as "comb jellies" due to their unique comb-like row of cilia.
