Truncate Clam (Mya truncata)
Please Note: This is a live marine specimen.

The Truncate Clam (Mya truncata) is a cold-water bivalve found in the mid- to lower intertidal zones of the Gulf of Maine, particularly in areas with strong tidal currents. Recognized by its shortened shell and visible siphons that often protrude above the substrate, this species is a fascinating example of adaptation to turbulent marine environments.

Collected by hand from sandy, high-current areas, these live clams are ideal for marine biology study, touch tanks, and coastal ecology lessons focusing on sediment-dwelling invertebrates and filter feeders.

Common name: Truncate clam
Scientific name: Mya truncata
Locations: Mid–lower intertidal in high current areas
Seasonality: Available all year
Colors: Sandy white and brown
Size: 1” – 3”
Collected: By hand (siphons easily visible)
Quantity: Sold by the each

Uses: Perfect for classroom study, aquariums, and marine ecology demonstrations.

Note: This is a live marine specimen. Natural variations in size, color, and appearance from photos should be expected. If you would like any specimen preserved, please send a request to: info@gulfofme.com.

Tidepool Tim says,  "Truncate clams are so amazing to find.  Usually, we are collecting along amid the rocks and they just sort of appear.  The thick siphon or neck really looks like an elephants trunk! At first, I thought we had discovered some sort of mutated soft-shell clam.  To accommodate the long thick siphon, the shells of the clam are bulged out on the sides. It appears that sometimes they are embedded in a substrate that somehow washes away with tidal currents as these clams can be found barely buried into the beach.  Truncate clams are bivalve filter feeders and live up to 10 years in age.”
