Many-Rayed Feather Star

Capillaster multiradiatus

Capillaster multiradiatus, known as the Many-rayed Feather Star, is a crinoid characterized by its numerous, slender arms that radiate from a central disc. This species can be distinguished from similar crinoids by its unique arm structure and the arrangement of its pinnules. The Many-rayed Feather Star typically inhabits tropical waters of the Indo-West Pacific, with recorded occurrences in regions such as Australia, New Caledonia, Palau, and Thailand. It is commonly found at depths ranging from 0 to 300 meters, although most sightings occur shallower than 90 meters. This species is a filter feeder, capturing small particles and plankton from the water column using its feathery arms. During reproduction, Capillaster multiradiatus engages in a gonochoric breeding strategy, where eggs and sperm are released into the water column during spawning. The fertilized eggs develop into free-swimming larvae before settling on the ocean floor and metamorphosing into adult forms. Diving encounters with the Many-rayed Feather Star can be intriguing, as they often perch on substrates in a range of habitats, including coral reefs and rocky areas. Observers may find them gracefully swaying with the currents, making for a captivating sight. The conservation status of this species is currently not evaluated, indicating a need for further research on its population dynamics and habitat requirements.
