How to recognize them

  • Thin, oval shells that gape at both ends; long fused siphon (“neck”) cannot fully retract.
  • Often coated in mud; broken white shells common on marsh edges.

Biology notes

  • Deep burrowers in soft mud; filter-feed via long siphons to the surface.
  • Sensitive to pollution and harvest pressure—closures protect public health.

Where to see them around Ocean City

  • Muddy bay flats and marsh guts around Assateague and mainland coastal bays.
  • Seafood menus as “steamers” when in season and open for harvest.

When to look

  • Year-round shells; diggers work cooler months when flats are open.

Viewing tips & etiquette

  • Soft shells crush easily—handle live animals gently if licensed to dig.
  • Never harvest from closed waters.
