Common Clam Shell Illustration - Marine Biology Reference Image #56096 (License: Personal Use)

This black-and-white line drawing depicts a closed bivalve shell-likely a hard clam (Mercenaria mercenaria)-with pronounced concentric growth rings and subtle radial striations. The shell’s umbo is elevated and slightly offset, indicating asymmetry common in many clams. Fine hatching adds texture and depth, characteristic of 19th- to early 20th-century scientific illustrations.
