Genus
Common name: Feather Star
Scientific name: Stephanometra
Stephanometra is a genus of crinoids, commonly known as feather stars, which are characterized by their feather-like arms used for suspension feeding. These echinoderms are popular in the reefkeeping hobby for their ornamental appearance and their role in nutrient cycling. They require moderate to strong water flow and access to suspended particulate food. Feather stars are sensitive to water quality and can be indicators of a well-maintained reef system. They are nocturnal and often display more activity during the night.
