7 Life Stages

Remark	Definition	Other Name	Public Name	Primary Identifier
	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.		L4.5 larva Ce	WBls:0000688
	The fourth sub-stage of the L4 larva. vulFs have separated and the apex of the lumen is flat and capped by the anchor cell. The uterine lumen starts to form. At 20 Centigrade: 38.1 hours after hatching, 4.1 hours from the L3-to-L4 molt.		L4.3 larva Ce	WBls:0000686
	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.		L4.2 larva Ce	WBls:0000685
	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.		L4.4 larva Ce	WBls:0000687
	The eighth sub-stage of the L4 larva. vulFs have migrated closer such that the lumen is narrowed in the dorsal section. The approximate cutoff is when the width of the channel is less than the width of the vulD nucleus. At 20 Centigrade: 42.3 hours after hatching, 8.3 hours from the L3-to-L4 molt.		L4.7 larva Ce	WBls:0000690
	The seventh sub-stage of the L4 larva. 'Fingers' between vulB2 and vulC are pointed ventrally. At 20 Centigrade: 41.5 hours after hatching, 7.5 hours from the L3-to-L4 molt.		L4.6 larva Ce	WBls:0000689
	The second sub-stage of the L4 larva. The inner cells of the vulva have finished migrating and have formed toroids, but have not fused. vulC and vulF have divided and a narrow lumen has formed. At 20 Centigrade: 35.1 hours after hatching, 1.1 hours from the L3-to-L4 molt.		L4.1 larva Ce	WBls:0000684
