bead anemone
Diadumene lineata
Family Diadumenidae

Jul 2024
Where
seen? This tiny anemone is often seen our Northern shores,
on hard surfaces near the high water mark. Usually in clusters
of many individuals rocky shores, jetty legs among encrusting animals like oysters, barnacles
and even inside the shells of dead barnacles.
Features: Tiny blobs less than 0.5cm. At low tide, they usually tuck their tentacles
into their greyish body column and look like tiny blobs with fine
stripes in white, orange, yellow or red. You will seldom see one with
its tentacles expanded at low tide.
This is considered one of the
most widely distributed anemone in the world and was probably
dispersed by ships. The anemone can reproduce by budding off from
the base and by dividing into two.
Status and threats: As at 2024, it is assessed not to be approaching the criteria for being listed among the threatened animals in Singapore.
