seen? These sea anemones with many fine 'branches' on their
tentacles are often seen on many of our shores. Among coral rubble,
usually with the body column wedged in crevices.

'branches'. Only one side of the tentacle appears to bear the 'branches'.
come in a wide variety of colours and their branched tentacles may
have different patterns. Also
sometimes encountered are branched sea anemones with tentacles that
are generally smooth with only slight bumps.
The body column is pale becoming darker near the top and has longitudinal
rows of white verrucae.
The anemone can tuck its tentacles into its body column.
Sometimes mistaken for other feathery
animals. Here's more on how
to tell apart feathery animals on our shores.
friends: The Frilly sea anemone harbours symbiotic algae
(called zooxanthellae) that photosynthesize. The algae share the food
produced with the anemone, which in turn provides the algae with shelter
and minerals. A pair of Peacock-tail anemone shrimps (Periclimenes brevicarpalis)
were seen once in a Frilly anemone.
and threats: Like other creatures of the intertidal zone,
sea anemones are affected by human activities such as reclamation
and pollution. Trampling by careless visitors, and over-collection
by hobbyists also have an impact on local populations.
