Regional Impacts
| Economic Impact | Shipping/Boating | |
| Fouling pilings, covering them with masses of tubes covered with sediment, but perhaps a benefit by discourage boring organisms (Barnard 1958). | ||
| Ecological Impact | Habitat Change | |
| Dense masses of corophiid tubes may discourage settlement by boring organisms and by other foulers, such as the tunicate Ciona intestinalis (Barnard 1958). They also may provide habitat for other organisms, such as predatory polychaetes (Barnard 1958). | ||
