Red fanworms have bodies which grow to 65mm in a tube of up to 10mm in diameter. They are lovely fanworms, having a white shell-like tube and two bright orange-red spirals of feathery branches protruding from it .
These animals are found off the southern African coast from Cape Point to Durban, subtidally and to at least 25m.
These animals grow under boulders or crevices, and are often seen on vertical rock faces. They use their feeding crowns to catch microplankton.
