 | | Whereas the body of an insect is divided into 3 parts--head, thorax, and abdomen--as has just been noted, the body of the spider is divided into 2 parts, the head and thorax being intimately fused into a cephalothorax and the abdomen being usually soft, rounded, and unsegmented (figure 35). |
 | | However, the abdomen is segmented, and consists of a large, anterior preabdomen or mesosoma of 7 segments and a long, narrow, tail-like posterior postabdomen or metasoma of 6 segments, terminating in a vesicle or telson bearing a venomous stinger. |
 | | The whip scorpion probably does not have a protective epicuticular wax layer, such as that possessed by insects and many other arthropods, to protect it from desiccation. |
