A comprehensive grid of meticulously detailed freshwater and saltwater fish species fills this natural history illustration, each specimen rendered in precise watercolor with subtle gradations of green, brown, red, and gold tones. The compositions is calm and orderly, presenting the fish in profile against a cream background with small identifying text below, evoking the scientific naturalism of classical ichthyology guides. Printed to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
