Regional Impacts
| Ecological Impact | Competition | |
| In experiments, Marenzelleria neglecta reduced the survival of Hediste diversicolor (Kotta et al. 2006). | ||
| Ecological Impact | Habitat Change | |
| In experiments, Marenzelleria neglecta enhanced the chlorophyll content of sediments, presumably by releasing nuritents, while burrowing (Kotta et al. 2006). | ||
