Pulmo Marina

Against a uniform background of purest Yves Klein blue, a pale yellow jellyfish roils and bristles like a fragment of living lace, while a slightly officious voiceover informs us of its baroque but literally brainless anatomy, its voracious cannibalism and its classical forebears (in French, such a creature is a méduse ). The apparently depthless blue is, were told, the rear of an elliptical tank at Monterey Bay Aquarium, in which the jellyfish is held in constant stasis by two opposing currents of seawater.
