The box jellyfish (class Cubozoa) is an invertebrate with a special way of viewing the oceans they swim in. These jellyfish have 4 different type of eyes, but a total of 24 eyes all over. Some can only detect light, and others are more complex, allowing them to see colors and size of objects. Two of the four types actually happen to resemble that of a humans! One of the upper lenses in the eyes helps them to stay close to mangroves, which is very useful considering if they stray too far they risk dying of starvation. The upper lenses are constantly focused upwards, which allows them to see the terrestrial world above. They also have lower lenses which provide vision to what is below them. This makes them rather good predators, since they can see what lurks both below and above. It also helps them to avoid colored obstacles, but not transparent since they have a very hard time seeing translucent objects. So, for not having a brain, I’d say these creatures are a lot more clever and evolved than we give them credit for!
