Most spiders have eight eyes. There are also six-eyed, four-eyed and two-eyed spiders. Some species of spiders that live in cave and other dark places have no eyes at all. A spider’s eyes are on the top and near the front of its head.
Even though a spider has so many eyes, it can only see things a few inches from its face. To make up for their nearsightedness, spiders have a very strong sense of touch and taste. Special hairs on the spider’s body contain nerves. These nerves act as “ears, nose and tongue” to sense danger, as well as to locate food.–Dick Rogers
