    // Sample output:

    // The image depicts a small, bright orange starfish (also known as a sea star) with five symmetrical arms radiating from a central disc. 
    // It has a textured, bumpy surface that gives it a realistic, almost spiky appearance, and there's a small hole or indentation at the center, 
    // which might represent the mouth or a natural feature. The starfish is shown against a plain white background, and it appears to be a simple, 
    // illustrative or clipart-style graphic rather than a photograph.
