Biological Notes
       Flabelligerids are heavily impregnated with sand or mud in a matrix of mucus (Fauchald 1977).   They are deposit feeders.   The food particles are collected by their large frilly paips or the dorsal semi-circle of branchial filaments.   Some genera are tubicolous while others creep about under stones or burrow just below the surface of the sand (Day 1967).
