Jumping spiders come in various colors like black, brown, tan, and gray, with white, gray, yellow, red, blue, or green markings. They are small, ranging from 1/8 to 3/4 inches, covered in shiny hairs. Their front legs are thicker and longer. These spiders have exceptional vision, detecting movement up to 18 inches away, but their night vision is not great. With eight eyes in three rows, the front has a large middle pair.
