If you’ve ever wondered what the mouth of a starfish looks like close up, this scanning electron microscope image shows the mouth and partial arms of a serpent starfish (Ophiura ophiura). These peculiar starfish search the seafloor for small animals or rotting flesh called carrion. Once a meal is within their grasp, they use their arms to tear it apart and move it to the central jawed mouth.
