Anthopleura buddemeieri
Family Actiniidae

Jul 2024
Where
seen? These small anemones are seen near the high water
mark on rocky shores made up of smooth boulders and rocks below a
thick coastal forest. Individually usually widely dispersed, seldom
with many on the same stone. First seen on St. John's Island, subsequently
found on other southern natural rocky shores.
Features: Diameter with tentacles
expanded 1-2cm. Pale body column with pink spots in rows along the
length of the body. One ring of tapering tentacles, pale greyish with
pinkish cast and pinkish tips.
When exposed to air at low tide, it tucks its tentacles into its body
column so it looks like a pink bead of jelly with tiny red spots. It looks
quite different from other bead anemones (Anthopleura sp.)
What does it eat? A study suggests they feed on isopods and amphipods.
Status and threats: As at 2024, they are listed as 'Endangered' in Singapore.
