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.

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.

Status and threats: Euryale aspersa is the only species of basket star is so far listed for Singapore. It is listed as "DD: EN? Data deficient, possibly Endangered" in the Red List of threatened animals.
