Genus
Common name: Brittle Stars
Scientific name: Ophiactis
Ophiactis is a genus of small brittle stars belonging to the family Ophiactidae. These echinoderms are known for their long, slender arms which they use for locomotion and feeding. They are nocturnal and often hide under rocks or within the substrate during the day. In the reef aquarium, they serve as a clean-up crew, consuming detritus and uneaten food. They are generally hardy and can adapt to a range of conditions, making them suitable for both beginner and advanced aquarists. Their ability to regenerate lost limbs is a fascinating aspect of their biology.
