Tentacles swollen just below the tip, though not always, which makes it harder to name than it sounds.
Disc to about 40 cm across, with tentacles that swell into a bulb just below the tip and taper again beyond it. The bulb is not reliable: the same anemone loses it under some conditions and shows plain tapering tentacles instead, which is a common cause of misidentification. Colour runs from brown-green to bright red.
It hosts the tomato and spine-cheek anemonefish in this region and, less often, Clark’s. It occurs both as large solitary individuals wedged into a crevice with only the tentacles showing and as dense clonal clusters covering a rock. It is the most numerous host anemone at the muck destinations. Recorded from about 2 to 30 m.
Ratings are per location: 1 means found on most dives that look for it, 5 means a handful of records. Where enough dives have been logged the figure is calculated from them; otherwise it is an editorial estimate, and says so. We publish habitat and destination, not the dive site.
