Study puff adder 

"Study puff adder" is a watercolor painting by Gustave Moreau. The piece depicts a puff adder in intricate detail. The artist's interest in the natural world is evident in the realistic portrayal of the snake's scales and markings. The work, currently housed in the Louvre, is a testament to Moreau's fascination with symbolism and the depiction of the macabre. The detailed study of the snake's form, its intricate markings, and its characteristic curled pose, speaks to Moreau's dedication to capturing the essence of his subject.
