  •   Info Cylinder anemone (Cerianthus membranaceusi), Arrábida Natural Park, Portugal. This tube-dwelling anemone has an oral disc with a diameter of up to 40 cm (16 in). There are two whorls of tentacles, amounting to about two hundred tentacles in all. Those in the outer whorl are long and slender and armed with cnidocytes (stinging cells) and are used for catching prey. Tentacles in the inner whorl are shorter and function to transfer captured food to the central mouth. This species is found on the seabed in shallow water in the Mediterranean Sea, the northern Adriatic Sea and the northeastern Atlantic Ocean, its range extending as far north as Britain. The tentacles of Cerianthus membranaceus do not retract, but the whole animal can retreat into its tube. As it does so, some of the tentacles grip the rim and pull the tube closed behind it, effectively making it disappear from view. The tube is normally a permanent home, but if the anemone is disturbed from below, as by a burrowing sea urchin, it can eject itself from its tube, move to a new location and secrete a new tube. C. membranaceus feeds on small fish and planktonic organisms which it catches with its tentacles. It is a protandrous hermaphrodite, starting life as a male and becoming a female later. The lifespan of C. membranaceus in the wild is not known, but some individuals have been occupants of a tank in Naples Aquarium for more than fifty years. Note: we have only this FP of this family (same species) but taken in an aquarium. c/u/n by Poco a poco (talk) 15:30, 8 July 2022 (UTC)[reply]

  •   Oppose QI for sure, but sorry, imo the background spoils it and there are more eye-catching specimens at category Cerianthus membranacea and more outstanding images at FP category. --Ivar (talk) 15:52, 8 July 2022 (UTC)[reply]
  • Yes you may be right, but those eye-catching images are either from an aquarium (where they usually use fluorescent light) or have little detail or a bad crop, I don't think that any of those images would have more odds to become FP than this one (my opinion, of course). Regarding the exiting FPs, well, I don't know, surely there are other anemones that look prettier with more colours and so on, but here I enjoy the amount of tentacles, the different types of them and the detail --Poco a poco (talk) 16:31, 8 July 2022 (UTC)[reply]
  • To be honest, I have been wondering the same. There is no coral in the Mediterranean Sea or in the Eastern Atlantic, so the background is typically just sand. The difference in color between the shorter and the longer tentacles is something I cannot explain. I googled but didn't find any reasoning for that.
