European Marsh Frog (Pelophylax ridibundus) - Detailed Illustration & Facts #3313663 (License: Personal Use)

This highly detailed vintage-style illustration depicts the European Marsh Frog (Pelophylax ridibundus), notable for its robust build, prominent dorsolateral folds, and vivid green-and-black marbled skin. The frog’s large, copper-orange eye and pale underbelly contrast sharply with its camouflaged back, highlighting key identification features used in herpetological studies. Fine linework and subtle shading suggest a lithographic or hand-colored engraving technique common in early natural history publications.
