Description
Size: Upto 500 mm diameter but commonly considerably less

Color: Oral disc usually purplish-gray to brown, sometimes with a green cast; tentacles basically same color but tips may be darker or lighter. Lower part of column dull orange to brilliant red, upper part brownish.

Tentacles few, long (to 175 mm), all alike, sinuous, evenly tapered to point, sometimes (but not invariably) assuming corkscrew shape. Oral disc widely flared, with radial white lines that may extend onto tentacles; lies at surface of sediment. Column buried in sediment; with non-adhesive, prominent white round to ovoid (eye-shaped) verrucae in longitudinal rows. When disturbed, tentacles may shrivel or may adhere to collector's hand and pull off. Can retract completely into sediment.

Found associated with zooxanthellae and with anemone fishes like Amphiprion chrysogaster, Amphiprion clarkii, Amphiprion frenatus, Amphiprion perideraion and Amphiprion polymnus. Also observed in association with Dascyllus trimaculatus and with shrimps like Periclimenes holthuisi.
