What is the characteristic color of the woodlouse spider's prominent chelicerae (jaws) against its dark carapace?
Answer
Pale or whitish
The chelicerae of the woodlouse spider are substantial, reflecting the strength required to pierce the tough exoskeleton of its primary prey, the woodlouse. A key detail used in confirming identification is the coloration of these powerful jaws. Despite emerging from the very dark, almost black cephalothorax, the chelicerae themselves are typically a pale or whitish color. This sharp contrast between the pale fangs and the dark surrounding material can be a reliable visual cue when observing a specimen in adequate lighting.
