Wiggly star anemone
awaiting identification*
updated Feb 09
Where seen? This elegant anemone with few arms held in wiggles is sometimes seen on many of our Southern shores among coral rubble and living hard corals. It is very shy and disappears instantly at the slightest sign of danger. Seen both at night and during the day.

Features: Diameter with tentacles extended 4-5cm. Small oral disk compared to the tentacles. Few tentacles (about 20). The tentacles are thick at the base and taper to a slender tip. Most of the tentacles are usually held flat against the surface, arranged in pairs or sets of three, with the tips in 'wiggles'. Often, 5 of the tentacles are held upright forming a 'tent' over the mouth. The mouth is often seen upturned.

The tentacles come in shades of blue, brown and red with paler tips. Sometimes with bands at mid-way along the tentacles, or a thin pink or orange stripe along the length from the tip. The body column appears to be covered with a leathery skin.
