![]() They usually have eight eyes: two very large front eyes to get a clear, colour image and judge distance, and extra side eyes to detect when something is moving. Jumping spiders are active hunters, like tiny lions chasing down their prey (bugs). But the kind of eyes they have tells us something about the food they eat and the lives they live. In fact, most spiders can’t see very well, and use touch and taste to explore the world. Spiders are also hunters and they need eyes that help them find and catch their food. That makes it easier for us to catch another animal so we can eat it. Having two big eyes in the front of our head means they can work together to guess how far away something is (we call this “judging distance”). Our eyes are very good at seeing colours and shapes. The short answer to your question is that animals have evolved different eyes that best suit the lives they lead.Ĭurious Kids: What are spider webs made from and how strong are they?
