Occurs at high densities where environmental conditions are suitable. For example, Magelona papillicormis has been reported at densities of 279 individuals per 0.1 m² on sandy muddy ground in the Elbe Estuary.
Magelona mirabilis feeds by gathering organic material from the sediment surface with its palps. When feeding on poorly sorted material, selectivity may be shown in that magelonids prefer to handle larger particles. Small crustaceans may also be taken as prey, for example, the mucous on the palps may trap a few harpacticoids although this is likely to be incidental. In well sorted sand, selectivity may be absent as particles with a high organic content have already been concentrated by other means.
