The comparison chart of the figure shows humans and porpoises at the top. Their eye is a barely discernible speck to the right.
Squids are next to the bottom of the chart with huge, dinner-plate size eyes.
Squids and humans evolved remarkably similar eye structures-each taking routes within their totally different groups to get to essentially the same place. Both squids and humans have eyes with single lenses, pupils, irises, and retinas even though squids evolved eyes under water and humans in the air. But, at the bottom of the chart, lies the all-time winner with the biggest eye of all. The Temnodontosaurs platyodon is an extinct sea reptile. They were not fish but rather ocean-going reptiles.
