This bronze articulated model of a spiny lobster dates to the 19th century Edo period in Japan and represents a remarkable example of naturalistic metalwork craftsmanship. The piece demonstrates the Japanese artisan's keen observation of marine life, with movable joints that allow the crustacean's limbs and antennae to articulate, showcasing both technical ingenuity and aesthetic appreciation for the subject. Such functional sculptures reflect the period's intersection of artistic skill and practical design, likely created for the appreciation of collectors or as a study of natural form.
