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).
