Where
seen? This intricate lace-like animals is sometimes seen
in the intertidal zone on some of our shores. Small ones seen clinging
to seagrasses, larger ones among coral rubble or wrapped around sea
fans.
Features: About 10cm in diameter
with arms. Each arm branched into coiling 'tendrils' that are highly
flexible. These eventually form a complex basket-like tangle that
is used to filter feed in the water. Each 'tendril' may be tipped
with a conical structure. Mouth on the underside. Some produced a
great deal of slime when handled. |

Baskets at home: According to David Lane, juveniles are often found on sea fans, while
adults are typically found under large corals and crevices during
the day, but at night climb up to an elevated point to unfurl their
arms into the current.
