The tentacles of a beautiful cerianthid or tube anemone were observed waving in the current during Windows of the Deep 2021 Dive 10 at 2,390 meters (1.49 miles) depth. Cerianthid or tube anemones belong to the subclass Ceriantharia and are rather distant relatives of sea anemones. All tube anemones have a quite uniform appearance, with an elongated body and two crowns of non-branched tentacles.
