An image of the face of an adult. SEM showing head morphology of the dauer larva. The material surrounding the amphidial pore presumably was secreted via the amphidial channel. Side view of the dauer larva shows a relatively flat contour. The two deirids are located dorsolaterally approximately 75um posterior to the region shown.
Intestinal cells contain electron-opaque storage granules.
The cytoplasm of the seam cells is less electron dense than the surrounding hypodermis. The cuticle has lateral alae. Section through pharynx showing the grinder. I-1 termini is labeled.
