This scientific illustration depicts a spider’s body segmented into the cephalothorax (prosoma), highlighted in yellow, and the abdomen (opisthosoma), shown in orange, with internal structures and surface patterns indicated. The cephalothorax features chelicerae, pedipalps, and leg articulations, while the abdomen displays digestive, reproductive, and spinneret regions. Stylized motifs-including a knuckle-duster symbol-suggest species-specific markings used in taxonomy or educational contexts.
