Feather Sea Star
Feather Sea Star
Himerometra species

Feather stars, also known as crinoids are very difficult to keep and maintain species and should be attempted by public aquariums, scientific study and other advanced aquarists who are knowledgeable of the feeding and care requirements of this species. The Feather Star have 5 arms but can have up to 200 for older, larger species. The pinnules, or arms, are coated with a sticky substance that filters small particulate matter from the water column. They prefer to cling to the underside of sponges, corals and rockwork and will come out to feed at night in the water column. Feather stars prefer strong currents that carry micro-plankton to them. Many animals live closely with feather stars such as crinoid shrimp, Squat Lobsters, and crinoid clingfish. They share the leftover food that the feather star collects and shelter in it's arms.

Due to the sensitive nature of this animals stringent acclimation requirements and sensitivity to being properly acclimated, it is on the Restricted Species List.
