Keywords:  zona, eclosion, pellucida, embryo, egg
A multi-step process, first described for C. elegans by Singh and Sulston (1978), by which the developing embryo makes an opening in the egg shell and exits this covering. Secretions from pharyngeal glands may promote he gradual weakening of the eggshell, which becomes visibly softer and more pliable in the hour just before eclosion. Once weakened, the motions of the three-fold embryo cause distortions of the whole shell and eventually the eggshell ruptures, allowing the new L1 larva to emerge from the broken shell. See Eclosion
Emerging from an egg.
Opening of the zona (outer shell of the egg) due to expansion of the volume of the embryo through repeated cleavage. It occurs a few days after the embryo arrives or is deposited in the uterus and immediately precedes implantation (see also ASSISTED HATCHING).
