Apr 24, 2012 · Similar to other nematodes, the life cycle of C. elegans is comprised of the embryonic stage, four larval stages (L1-L4) and adulthood. The end of each larval stage is marked with a molt, during which a new, stage-specific cuticle is synthesized and the old one is shed.
Caenorhabditis elegans - Wikipedia
Anatomy and scale of C. elegans developmental stages Life cycle and developmental stages of C. elegans. Under environmental conditions favourable for reproduction, hatched larvae develop through four larval stages - L1, L2, L3, and L4 - in just 3 days at 20 °C.
In favorable environments, C. elegans undergoes reproductive development and progresses rapidly from embryo through four larval stages (L1–L4) to the adult in 3–5 d (15°C–20°C). Adults then live another 2–3 wk.
A Transparent window into biology: A primer on Caenorhabditis elegans …
C. elegans has a rapid life cycle (3 days at 25° from egg to egg-laying adult) and exists primarily as a self-fertilizing hermaphrodite, although males arise at a frequency of <0.2% (Figure 2). These features have helped to make C. elegans a powerful model of …

Life cycle of the C. elegans hermaphrodite at 22°C. An adult hermaphrodite with developing oval-shaped embryos inside is shown at the top of the life cycle. Once the embryos reach the 28–30-cell stage, they are laid into the environment and continue to develop.

Life Cycle of C. elegans. Animals increase in size throughout the four larval stages, but individual sexes are not easily distinguished until the L4 stage. At the L4 stage, hermaphrodites have a tapered tail and the developing vulva (white arrowhead) can be seen as a clear half circle in the center of the ventral side.
Embryo Introduction - Wormatlas
Nov 1, 2017 · The embryo of the nematode Caenorhabditis elegans progresses through several distinctive phases in developing towards the first larval stage, when the embryonic worm first emerges from the eggshell.
Life History And Evolution - C. elegans II - NCBI Bookshelf
Both the rapid life cycle (14-hour embryogenesis and 36-hour postembryonic development through four larval stages, L1—L4 to the adult at 25°C) and large brood size favor this strategy, but a compromise must be reached between these two traits.
Introduction to Germ Cell Development in C. elegans - PMC
Wild-type C. elegans progress through their life cycle in about 3.5 days at 20° C, under optimal laboratory conditions, including constant temperature and unlimited food (equivalent to “feasting at the Hilton”).
An Overview of C. elegans Biology | SpringerLink
The life cycle is rapid. At 25°C, embryogenesis, the period from fertilization until hatching, occurs in 14 h. Postembryonic development occurs in four larval stages (L1–L4) that last a total of about 35 h.
