Ctenophores, commonly known as comb jellies, are beautiful marine invertebrates with eight rows of cilia that they use for propulsion. There are several synonyms for these fascinating creatures, including Ctenophora, sea gooseberries, sea walnuts, Venus's girdles, and Beroe. Ctenophora comes from the Greek word "cteno," meaning "comb," and "phora," meaning "bearer." The name sea gooseberries refers to their round, translucent bodies that resemble small berries. Sea walnuts have a walnut-like shape, while Venus's girdles were named after the Roman goddess of love and beauty due to their mesmerizing appearance. Lastly, Beroe is a genus of ctenophores that are notable for their bioluminescence.
