Flatworms only have two scattered dot-like eyespots for sensing light. More complicated vertebrates have eyes that can formulate and focus on images. Although flatworms are mostly predatory in nature, their eyespots can only differentiate between light and dark. The hermit crab Dardanus calidus is a visually sensitive and agile creature. Any sign of movement will make it retreat into its shell while sticking out its eye rods as a form of surveillance. Vertebrates such as the scorpionfish (Scorpaenidae) have lens and retina comparable to those of humans.

Taken at a tide pool on the Magang platform, New Taipei City, between February and November 2014. When photographing marine creatures' eyes close up, one must have keen observation skills and great patience in wavy waters. A single flash (Nikon SB-28) or a built-in LED light (TG-3) was used to imitate the sunlight. The color of the image was compared to the actual color of the object using the naked eye. Images 1 and 2 were taken with Nikon D7000, flash unit SB-28, 60mm, F2.8 macro lens and Kenko1.4 diopter lens, and Ewa-Marine waterproof housing to capture the marine creatures in the tide pool. Image 1: The tiny eyespots of the flatworm were photographed using ISO 400, manual controlled (M) mode, speed: 1/350, f/54, flash 1/2. Image 2: The green compound eye of the hermit crab was photographed using ISO 400, M mode, 1/1250, f/38, flash 1/2, TG-3. Color adjustment and contrast were carried out in Photoshop. Image 3: The predatory scorpion fish equipped with precise vision, was photographed using OlympusTG-3 camera, with ISO was set to auto-macro mode, 1/1250, f/16.48, natural lighting and built-in LED for additional lighting.
