The image is an underwater photograph of a large crab in an aquarium. The crab is standing on its hind legs with its front legs stretched out in front of it. It has a long, slender body with multiple legs that are spread out in all directions. The body of the crab is covered in small rocks and pebbles, and its legs are long and thin. The background is dark, and the crab appears to be in motion, as if it is moving through the water. The image is taken from a low angle, looking up at the crab.
