C. elegans Life cycle
Life Cycle of C. elegans at 25°C:
- Solid arrows: moltsG
- From Egg to LarvaeG 1 (L1) stage:
it takes 8 hours from the laying of egg to L1 stage. The whole embryogenesisG
from sperm entry to hatching takes about 14 hours.
- The DauerG
stage: C. elegans develops into dauer larvae stage under
- From Dauer to L4: after placing in food, dauer
larvae will reach L4 stage.
- Its life cycle is about 3 days.

Dauer: a developmental
stage of C. elegans that occurs under starvation conditions
in which the larva enters developmental stasis. With food, the dauer
larva can reach L4 stage and then become an adult.
