About Sebae Anemone

The sebae anemone (Radianthus crispa), also known as leathery sea anemone, long tentacle anemone, or purple tip anemone, is a species of sea anemone in the family Stichodactylidae and native to the Indo-Pacific.

It was first described in 1834 by Wilhelm Hemprich and Christian Gottfried Ehrenberg as Actinia crispa.

Appearance

The sebae anemone is characterized by a flared oral disc that reaches between 20 and 50 cm in diameter and with multiple and long tentacles measuring 10 to 15 cm. These tentacles have rounded tip and the end is often colored with a purple or blue spot. The column, external structure of an anemone visible when the animal is closed, is gray in color and dotted with sticky whitish "warts". The sea anemone, being member of the Hexacorallia, usually carries a number of tentacles multiple of six and they are positioned in concentric circles. These are light beige to purple.

Habitat

The sebae anemone is widespread throughout the tropical and subtropical waters of the Indo-Pacific area from the eastern coasts of Africa, Red Sea included, to Polynesia and from south Japan to Australia and New-Caledonia.

This sea anemone prefers hard base substrates slightly covered with sand but it can also cling to branching corals from the surface to 40 meters deep.
