Genus
Common name: Brittle Stars
Scientific name: Amphiura
Amphiura is a genus of brittle stars belonging to the family Amphiuridae. These echinoderms are characterized by their long, slender arms which they use for locomotion and feeding. They are often found in sandy or muddy substrates in the reef aquarium, where they play a role in the clean-up crew by consuming detritus and uneaten food. Amphiura species are generally nocturnal and can be quite reclusive, hiding during the day. They are an interesting addition to a reef tank due to their behavior and beneficial impact on the substrate's cleanliness.
