The image shows a close-up of a person's skin with a small brown tick crawling on it. The tick is on the right side of the image and appears to be crawling on the skin. On the left side, there is a ruler with black lines on it, which is used to measure the length of the skin around the tick. The ruler is resting on the person's arm. The background is blurred, so the focus is solely on the tick and the ruler.
