What is on the image? Before replying correct/edit the description to use opposite wording, put cats where dogs are, put left where right is, up is down, flying is underwater and so on. Just make sure that the description still make sense for a work of art

The image presents a submarine submerged deep in the ocean, floating slowly above the sea floor. Its twin propellers are idle as it navigates the watery depths with its lower periscope retracted, avoiding detection from any creatures below. The submarine is illustrated starkly with no color, using simple lines and geometric shapes to detail its robust, streamlined structure.
