| | The 14 segments that are fused together to make up the cephalothorax are called somites and each somite bears a pair of appendages that are located on different areas of the lobster, usually on either side of the body or on the underside of the body. | | | Twenty pairs of gills located within the branchial chambers on either side of the cephalothorax are what comprise the respiratory system. | | | The digestive, excretory, respiratory, circulatory and reproductive systems of the lobster are located within the cephalothorax, below the carapace. |

| | The body structure of a spider is similar to that of other arachnids in being divided into an anterior cephalothorax, or prosoma, and a posterior abdomen, or opisthosoma. | | | Although most are less than 1 cm (less than 0.4 in) long, the largest has a body length of about 9 cm (about 3.6 in), and spider leg spans can be much greater. | | | The two parts are separated by a narrow stalk, or pedicel, which gives the animal a flexibility that facilitates its use of silk. |
