Fig. 5From: Capture silk scaffold production in the cribellar web spiderHigh magnification scanning electron micrographs of the cribellate spigots in N. albofasciata. a-c Cuticular surface of the cribellum is covered by hundreds or thousands of tiny, elongate spigots, each producing a single fibril of cribellate silk. d-f All of these spigots are composed of five tubal segments with four thicker regions. Each cribellar spigot shows segmented flexible structure which enable to bent itself and conjoin together with adjacent spigots. Scale bars indicate 1 μm (a) and 0.5 μm (b-f)Back to article page
