The eye of a spiny starfish. A red fleck at the tip of each of the starfish's arms is a concentration of sensory cells that allows light-dark perception. As different species have adapted to meet specific needs and inhabit varied environments, the eye has evolved with an extraordinary diversity of specialization.
