Silt Sand Mud
Marine Silt, Sand, and Mud
Collected from Active Gulf of Maine Mudflats
Authentic marine silt, sand, and mud collected by hand from the intertidal mudflats of the Gulf of Maine. This natural substrate contains native microorganisms, organic material, and fine sediment textures representative of real coastal marine environments. Ideal for marine biology labs, aquarium setup, sediment analysis, and benthic ecology studies, this material provides a true-to-nature base for marine tanks and classroom research.
Each collection is gathered fresh to order, ensuring a clean and authentic representation of Gulf of Maine substrate — rich in both texture and ecological value.

Clam holes! Clams beneath the surface of the mud are sitting right above thick marine clay. Their siphons extend through the muddy layer to the oxygen rich surface.
