This artwork demonstrates the talent of Marcus Elieser Bloch at depicting the features of the Cottus Scaber fish using the techniques of ichthyological illustration in the 18th century. It can be noted that the fish under consideration possesses a well-developed system of vertical saddle bands located on its body, which is accompanied by complex dorsal fins and armored head.This rare antique copper engraving is decorated with the plate typography in the top right corner and represents an excellent combination of precise scientific taxonomy and natural camouflage. This is a unique decoration of the antique natural history, marine biology, and classical gallery lovers.
