Lebrunia neglecta reaches 30 cm diameter. Caribbean anemone (Aliciidae) with central disc brown to gray, particular by its double crown: branching pseudo-tentacles khaki-brown to olive-green evoking algae tuft mimicking Padina or Dictyota deployed by day for photosynthesis (zooxanthellae), and true urticating tentacles deployed at night for prey capture. Lives from 3 to 30 m on Caribbean coral and rocky reefs. Can inflict stinging burns. Sometimes hosts shrimp (Periclimenes). Unusual dive photo subject, often mistaken for a plant by inexperienced divers.
