Mussels filtering water

Mussels are filter feeders. They draw in seawater and filter out phytoplankton and sediments, cleaning the water as they go.

This 25-second video is a before and after display of murky seawater, demonstrating the ability of mussels to help clear it.

The video was produced by Revive Our Gulf, the flagship organisation for the Mussel Reef Restoration Trust.
