Which Spiders Have 6 Eyes?
WouterSpiders are important members of the environment. They have evolved special adaptations for hunting insects. These include two sets of eyes for sight and another set for touch. They also have specialized eyes for detecting movement.
All spiders have eyes, but not all of them are used in the same way. Several species have only six eyes, and other species have twelve or more. The arrangement of eyes helps arachnologists identify a spider’s family and species.
The number of eyes is important for classification purposes, but they also help spiders detect and respond to motion. An even number is always best. A brown recluse spider has six eyes in three pairs. It is also called a fiddleback or violin spider.
In addition to their primary eyes, some species have vestigial or secondary eyes. These eyes are smaller than the main eye and are usually oval or round. They may be located on the side of the head or in the back. Some spiders have a small violin-like mark behind their eyes.
Some spiders have a specialized eye for locating prey. This helps a spider detect and avoid potential threats. It is also helpful for hunters to recognize a potential mate. A spider that does not have eyes can still hunt.
Many spiders have special adaptations for eating. Spitting spiders eject sticky fluid to subdue their prey. They are also known for their ability to lure their prey to the edge of a web.
