Class
Common name: Feather Stars
Scientific name: Crinoidea
Crinoidea, commonly known as feather stars and sea lilies, are an ancient class of echinoderms characterized by their distinctive feather-like arms. They are primarily sessile or free-swimming and are found in both shallow water and deep-sea environments. Crinoids are filter feeders, using their arms to catch plankton and detritus. In the aquarium, they can add a unique and exotic touch but require stable water conditions and low to moderate flow to thrive. They are also known for their regenerative abilities, able to regrow lost arms.
