However, that group of animals went extinct a long time ago. According to scientists, there once existed an ocean animal known as trilobites, which had lenses made from limestone. Weird, huh? And the reason they have so many eyes is most likely a backup since their eyes can literally erode.Ĭhitons may be the only species with rocky eyes like this. Interestingly, the lens of each eye is made from the same material as its shell, so it’s basically like rock. ChitonĬhiton, otherwise known as sea cradles, loricates, or polyplacophorans, are sea creatures that have thousands of tiny eyes on their shell – all featuring a light sensitive cell and a lens. Sure, they look a little terrifying, but all those eyes are there to keep him safe and thriving. Thus, they need eyes in all areas to be able to see everything – and their eyes do different jobs.Ī spider’s large central eyes are best for discerning shapes, while its side eyes play an important role in spotting predators. Spiders, for instance, do not have necks, so they can’t turn to look at things. One reason human eyes are different to spider eyes is because we’re built differently. Well, it’s not as straightforward as that. You might be wondering why spiders need eight eyes when we get on perfectly well with two. They usually have eight eyes: two huge ones at the front to see color and distance, and extra side eyes to detect movement. Jumping spiders are active hunters, so they need razor sharp eyesight to be able to track down their prey. Butterflies can see lightwaves from 254 to 600 nm – an asset they use to search out food, identify predators and seek a suitable mate.īutterfly species with exceptional vision include the Monarch Butterfly and Australian Swallowtail Butterfly. The single eyes focus mainly on individual objects, while their 12000 compound eyes are used as their primary eyesight. Some of them are single eyes and others are compound eyes. Research shows that butterflies have approximately 12000 compound eyes. The main role of their eyes is to distinguish movement and light from dark. ![]() Surprisingly, scorpions can’t see very well at all. With all those eyes, you’d think the scorpion had exceptional vision. Scorpions have eight legs, two main body regions, and up to twelve eyes (or five pairs), depending on the species: two eyes on top and two to five lateral eyes on the side. However, like every animal in the kingdom, there’s a logic behind their capabilities. Compared to other animals out there, a starfish’s vision is pretty limited – even with those extra three eyes. They’re known as eyespots, and while they can’t detect color or fast-moving objects, they can see light and dark and even large structures. They have five – one on the tip of each arm. Starfish don’t have regular eyes like you and I. Next time you see a bee buzzing about, try to steal a little glance and see if you can spot those additional eyes! Starfish Both sets of eyes play different roles, but are crucial for keeping bees thriving. The two large eyes at the side of a bee’s head (known as compound eyes) are used for distinguishing shapes and colors in their immediate environment, whereas the three small eyes on the top of the head (ocelli) are essential for navigation. This insect needs eyes not only to see colors and UV markings in flowers, but also to navigate. Beesīees are known to have five eyes: two compound eyes and three eyes known as ocellus or ocelli. And their regular eyes pitch in to help as they can see movement at large distances. It’s definitely handy having that extra eye as it keeps them safe. While it can’t discern shapes or color, it does discern light and movement, enabling iguanas to spot predatory birds from above. They have a third eye on top of their heads, known as the parietal eye. Iguanas are herbivorous lizards commonly found in Mexico, Central America, South America, and the Caribbean. If you’re curious about animals with the most eyes, meet the animals that have more than two eyes. ![]() Since our body structures different so significantly, certain animals need multiple eyes in order to see their full surroundings. For some invertebrates and mammals, additional eyes help them spot and hunt prey. For some fish and amphibians, that extra eye or two helps them to regulate their body temperature and find their way around via the sun’s light. Those additional eyes aren’t there for no reason. And then there are the animals that have 360-degree vision. Some animals, for instance, have far better hearing and sight than us. Then again, the animal kingdom is a fascinating world of unique and interesting surprises. Since you and I (and our pets) only have two eyes, it can be hard to believe that there are animals out there with multiple eyes.
