Distribution

These animals are found off the South African coast from the Cape Peninsula to Mozambique as well as circumtropically. They are seen subtidally, up to at least {{Convert|51|m|ft|abbr=}} deep.

Ecology

Elegant feather stars are usually found singly on shallow reefs and are more abundant on deeper reefs. If displaced they may swim using their arms. Commensal organisms such as the myzostomid worm Myzostoma fuscomaculatum and the crinoid shrimp Hippolyte catagrapha are found on the specimens found in False Bay.
