C. veneris, also known as Venus Girdle, are long, flat, slender ctenophores. They grow to be about five feet long, but are only three inches wide. C. veneris are usually light violet in color, and found near the surface of the Atlantic and Pacific Oceans, the Mediterranean Sea, and various Antarctic waters. Their bodies are very delicate and can be easily broken apart by divers or attempted collection. Like other ctenophores, they capture and consume mollusks and small crustaceans using very small tentacles on the surface of its body.
