Which sense is *not* considered the primary input for hunting by the woodlouse spider?
Answer
Vision
The eyes of the woodlouse spider are described as simple and typically arranged in a compact group. This morphology indicates that vision is not the spider's principal sense relied upon for locating and capturing prey. Instead, like many ground-dwelling, nocturnal hunters, *D. crocata* relies more heavily on cues derived from touch (vibration or substrate movement) to detect the presence and movement of the heavily armored isopods in dark conditions. This sensory profile confirms its divergence from highly visual hunters.
