 Jumping Spider 

 

Spider eyes can range from creepy to fascinating, depending on the person. With anywhere from 0 to 8 eyes and a wide variety of ways in which they see, spiders have been the subject of research on eyesight for years. While there is still much to be discovered, here are some things that we do know about how spiders see the world.

Unlike insects that have compound lenses, spiders have one simple lens for each eye. Most spider species have 8 eyes arranged in various configurations, but some have 6 or fewer. There is even a species of cave spider that does not have eyes at all because it lives in almost complete darkness. 

The majority of spiders, despite having many eyes, do not see well. They can detect changes in light and dark, but often little else. This means that they must use other senses to help them eat, mate, and get around in the world. They rely on touch, taste, and extreme sensitivity to vibrations. 

Different spider species have eyes that function in different ways based on their environment and behavior. Web-building spiders may only see a blurry image, but their sensitivity to vibration is well-developed so that they can feel prey on their silk webs. On the other hand, spiders that hunt for their prey, like jumping or wolf spiders, have much sharper eyesight to meet their needs.

Many researchers have studied the eyes of jumping spiders, which are hunting spiders that tend to have excellent vision. They are fascinating because they have three different types of eyes that see things in 3 different ways, from wide-angle to clear and focused, to better for depth perception. The eyes are arranged in a way that allows the jumping spider to see all around. On the top of the head are 2 tiny eyes and 2 medium eyes that help see blurry, wide-angle images. On the front of the head are 2 huge eyes (for sharp, focused details) and 2 small eyes (to sense motion). Having all of these eyes, helps make jumping spiders formidable hunters. This is just one example of how spider eyesight has developed.

First, we can acknowledge that the world is full of amazing creatures, but many of them, like spiders, are still best admired in nature and not in the home. It also goes to show that there are many unique types of spiders that behave, get food, make homes, and even see the world differently.
