Take a long look into the face of the world’s largest two-dimensional wheel-web weaving spider: The Golden Orb-weaver (Nephila pilipes).
The red appendages, projecting forward from the head region, are sensory organs called palps. They detect scent, sound and vibration. Between them are the powerful chelicerae; made up of the base segment and the fangs. Above, the cephalothorax houses six eyes with a three-dimensional outlook.
Gigantism in these animals correlates with increased temperature, so I suppose it is inevitable that we should all enjoy a closer familiarity in this anthropogenically-exacerbated interglacial warming period.
