Bivalve Shell Illustration - Scientific Drawing of Clam or Mussel Shells #3061691 (License: Personal Use)

This black-and-white engraved illustration depicts two bivalve mollusk shells, likely representing a clam or mussel species. The foreground shell is closed, displaying pronounced concentric ridges and fine striations, while the background shell lies partially open, exposing its inner surface and hinge structure. Fine cross-hatching conveys texture, depth, and natural wear, typical of 19th- to early-20th-century biological illustrations.
