| Ecological Impact | Habitat Change | |
| Codium fragile attaches to stones, and was observed to increase the transport of stones onto a sand beach, with the potential to change it to a gravel beach (Nobska Beach, Woods Hole) (Ben-Avraham 1971). However this beach was still mostly sand in 2015 (Paul Fofonoff, personal observation). | ||
| Economic Impact | Aesthetic | |
| Accumulations of Codium fragile on Cape Cod beaches are unattractive and unpleasant to walk on, perhaps more so than most seaweeds (Fofonoff personal observation). | ||
