The arrangement of eyes is often used as an identification feature for different spider families. • Spider eyes are typically small and spherical, with a shiny appearance. They are usually positioned on the front part of the spider's cephalothorax, which is the fused head and thorax region. The size and color of spider eyes can vary, ranging from black or dark brown to lighter shades. • The arrangement of eyes can differ between species, but a common pattern is a set of four smaller eyes in a row at the top, followed by two larger eyes below. The larger eyes are often the most prominent and provide the spider with better vision. These eyes are called the principal eyes or anterior median eyes. • Each eye has a transparent covering called the cornea, which protects the eye and helps focus light. Behind the cornea, there is a lens and a layer of light-sensitive cells called the retina. Spiders don't have muscles to control eye movement, so they rely on moving their entire body to change their field of vision. • Spiders' eyes are well-adapted for detecting movement and light intensity, but their vision is generally not as sharp or detailed as that of humans. However, some spider species have specialized visual adaptations for hunting or sensing prey.
