Gonophores develop between the two whorls of tentacles, and produce either eggs or sperm. The fertilized eggs are retained within the gonophores and develop into actinula larvae, which emerge from the gonophore and then settle on the bottom. The actinula larvae attach and undergo metamorphosis into juvenile polyps. Upper Newport Bay, Newport Beach, Orange County, CA. 3/29/09. © Peter J. Bryant
