The image shows a person holding a yellow ruler in their hand, with a jellyfish in the water and foam surrounding it. The jellyfish appears to be a horseshoe crab, with its long, slender body and round head. Its tentacles are spread out, and its eyes are wide open, giving it a curious expression. The person's hand is visible, gripping the ruler firmly, ready to measure the size of the jellyfish.
