<i>Siphonophore Rhizophysa</i> (IMAGE)
Caption
Three views of one twilight zone animal-- the predatory Siphonophore Rhizophysa--look like a magical dancing sprite in the night sea. A relative of the Man-o-War, it's four inches high when contracted (middle) but its stinging tentacles stretch to a couple of feet when fishing.
