This image is a black-and-white line drawing containing several stylized marine and freshwater creatures arranged without overlapping, on a plain background. The image components, from top to bottom and left to right, include1. A mollusk-like creature with a spiral shell and a simple face indicating eyes and a mouth. The body extends from the shell in a worm-like form, ending in a tapered head with two point-like sensory extensions at the front.2. Beneath the mollusk, there is a fish depicted with horizontal lines across its body, simulating either scales or motion blur. The fish has a dorsal fin, detailed with vertical line strokes implying texture or segmentation. The gills and eyes are indicated with simple lines and a dot, respectively. The fish is shown in profile, with a closed mouth and streamlined body emphasizing swift movement.3. To the right of the mollusk, overlapping with the fish described above, is a large crayfish or crustacean-like figure. It has a segmented body, visible as various distinct armored sections, and a tail fan comprising multiple feathered elements. Its appendages include two prominent pincers, one raised above its body, appearing segmented and ending in points typical of grasping claws. The depiction includes multiple legs beneath the body, also segmented.4. Below the crayfish, towards the center and right of the image, stands a stylized representation of a jellyfish. It shows a bell-shaped body with undulating edges suggesting motion or fluidity. From the bell, numerous tendrils extend downward, varying in thickness and length, some of which split into two tips. These tendrils suggest the jellyfish''s tentacles, commonly used for locomotion and feeding.5. On the lower left, a horizontally oriented fish appears more elongated than the first, resembling an eel or a similarly shaped species. It has fewer detailed features compared to the other depictions, but includes an eye, dorsal fin stroked with lines parallel to the
