The image is a vintage-style illustration of a jellyfish. It's rendered in a delicate, watercolor-like style with a pale yellow background. The jellyfish has a translucent, bell-shaped body with radial lines of a reddish-orange hue. Numerous thin, flowing tentacles extend downwards, also in shades of orange and red. The tentacles are intricately detailed, appearing almost hair-like. The overall aesthetic is reminiscent of a scientific illustration from an old natural history book. The top left corner reads 'MAYER' and the top right corner reads 'PLATE 64'. There is a small inscription in the bottom right corner that is difficult to read.
