Description |
Orbweavers are very diverse in size, shape, and color. They have eight small eyes in two rows. The lateral eyes are usually well separated from the median eyes. The median ocular area (MOA), the area defined by the middle four eyes, is in the shape of a trapezoid. The front part of the body (carapace) is smaller than the rear part (abdomen). The abdomen is large, rounded, and marked with lines, spots, or zig-zag patterns. The legs are short and spiny. The first and second pairs of legs project forward, the third and fourth pairs project backward. There are three claws at the end of each leg, though these are not visible without magnification. Females are much larger than males. |
