- L4.0 larva Ce
importer/temp
[:life-stage/id "WBls:0000683"] :life-stage/definition The first sub-stage of the L4 larva. All vulval cells are migrating toward the center of the future vulva. vulA, vulB, and vulE have divided, but vulC and vulF have not. At 20 Centigrade: 34.3 hours after hatching, 0.3 hours from the L3-to-L4 molt.
- L4.2 larva Ce
importer/temp
[:life-stage/id "WBls:0000685"] :life-stage/definition The third sub-stage of the L4 larva. All vulval cells complete migration. vulA, vulC, and vulD undergo cell fusion. The vulval lumen has widened and a prominent kink has formed between vulC and vulD. The uterine lumen has not started to form. At 20 Centigrade: 36.8 hours after hatching, 2.8 hours from the L3-to-L4 molt.
- L4.8 larva Ce
importer/temp
[:life-stage/id "WBls:0000691"] :life-stage/definition The ninth sub-stage of the L4 larva. The vulval lumen is partially collapsed. At 20 Centigrade: 42.5 hours after hatching, 8.5 hours from the L3-to-L4 molt.
- L4.9 larva Ce
importer/temp
[:life-stage/id "WBls:0000692"] :life-stage/definition The tenth sub-stage of the L4 larva. The vulval lumen is completely collapsed. At 20 Centigrade: 42.8 hours after hatching, 8.8 hours from the L3-to-L4 molt.
- L4.5 larva Ce
importer/temp
[:life-stage/id "WBls:0000688"] :life-stage/definition The sixth sub-stage of the L4 larva. The side of the vulval lumen between vulC and vulD forms a smooth curve. At 20 Centigrade: 40.4 hours after hatching, 6.4 hours from the L3-to-L4 molt.
- L4.4 larva Ce
importer/temp
[:life-stage/id "WBls:0000687"] :life-stage/definition The fifth sub-stage of the L4 larva. utse is visible as a thin layer separating the vulval and uterine lumens. 'Fingers' are formed at the sides of the vulva next to vulB1 and vulB2. The uterine lumen is fully distended. At 20 Centigrade: 39.0 hours after hatching, 5.0 hours from the L3-to-L4 molt.

- elongating embryo Ce
importer/temp
[:life-stage/id "WBls:0000015"] :life-stage/definition The C. elegans life stage spanning 350-620min after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. The stage that embryo starts elongation until elongation is over.
- 1-cell embryo Ce
importer/temp
[:life-stage/id "WBls:0000006"] :life-stage/definition Also called zygote. -50min till 0min of first cleavage at 20 Centigrade. Contains 1 cell.
