- inactive phase short
The period during which a worm usually does not lay eggs is short compared with control animals, based on the analysis of the distribution of the log intervals of egg-laying events.
- egg laying irregular
The rate of the intrinsic behavioral program that serves to move fertilized eggs down the uterus, through the vulva, and out of the worm onto the substrate does not conform to the pattern observed in control animals (Wormatlas).
- paralyzed
Animals do not move and are not responsive to external mechanical stimulation.
- bag of worms
A worm carcass is formed with retained eggs that hatch inside.
- rubber band
When prodded on the head, worm contracts and then relaxes along its entire body without moving backwards, compared to a control worm which contracts its anterior end and backs away in response to prodding.
