| The Gem Shell is also a filter feeder and only 4 mm in size, but it occurs in very dense populations. |
| This filter feeder, if established, would compete with native fishes for plankton. |
| The common cockle Cerastoderma edule is a bioturbating filter feeder that is widespread along the European Atlantic coastline. |
| The Round Pigtoe is a filter feeder, consuming bacteria, algae, organic detritus and protozoans. |
| This is expected to have positive effects on higher trophic levels, such as fish, and improve water quality, by enlarging filter feeder biomass. |
| The team also recorded an invasive species of marine invertebrate filter feeder. |
