mudflats
Exposed coastal sediment
Mudflats are flat expanses of mud exposed at low tide along coastlines and estuaries.
These tidal zones support distinctive ecosystems—shellfish, worms, and the shorebirds that feed on them.
The surface appears barren but teems with life beneath.
We walked across the mudflats at dawn, watching sandpipers probe the muck.
