What is another word for Phylum Ctenophora?
Pronunciation: [fˈa͡ɪləm sˈiːtˈɛnəfˌɔːɹə] (IPA) 
Phylum Ctenophora, also known as comb jellies, is a group of marine invertebrates with distinctive cilia-covered tentacles. Synonyms for this phylum include Ctenophores and sea walnuts. The term Ctenophora comes from the Greek word for "comb-bearer," referring to their comb-like rows of fused cilia which they use for swimming. These gelatinous creatures are mostly transparent and come in a variety of sizes, from tiny species nearly invisible to the naked eye to the enormous Venus's girdle, which can reach up to 40 meters in length. Unlike jellyfish, comb jellies do not sting and are a vital food source for many marine organisms.
