Where seen? This rather large cerianthid with a dark centre and neon colour combination is sometimes seen on some of our shores. Among coral rubble, near seagrasses.

Features: 12-15cm in diameter. The very long tapering outer tentacles are transparent to pale white. In some, the pale outer tentacles have a pair of thin darker stripes. The 'mouth' is very dark brown to black while the short inner tentacles are usually a pale neon green. Body column black.
