About
Radianthus doreensis, known as the long tentacle anemone or corkscrew tentacle sea anemone, ranges from Japan south to the waters of New Guinea and northern Australia. It is commonly found on muddy bottoms at depths of 5 m or less, though SeaLifeBase records it to 15 m. It has relatively few tentacles, all alike in size and colour, purplish-grey to brown, sinuous and tapering evenly towards the tip, sometimes forming a corkscrew shape. The oral disc is also purplish-grey to brown, sometimes with a green cast, with white radial lines that sometimes extend onto the tentacles. It keeps its column buried in the sediment with only the oral disc at the surface; the lower column is dull orange to bright red and the upper part brownish, with rounded to ovoid verrucae in longitudinal rows. When disturbed, the tentacles either shrivel or stick to the hand, and the animal can retract entirely into the sediment. It hosts four species of anemonefish plus the threespot dascyllus.
