Translations:Codex: Nyrea/12/en

Female nyrea, upon extraction of sperm from a mate, will fertilize between six and ten large eggs. Eggs are deposited via the pseudo-penis, which is by necessity very elastic and hollow. Nyrean females have a remarkable versatility when it comes to laying eggs, and individuals show marked variance in response to impregnation. Some will bear the eggs inside themselves until nearly time to hatch, while others will oviposit the eggs into the male that fertilized them, much as in Terran seahorses (this indeed seems to be the most common method, and the male genital slit and reproductive cavity seem remarkably well-adapted to this role). Some “alpha” females will attempt to dominate other, weaker nyrean females and deposit their eggs inside the defeated female (either anally or via the beaten female’s own pseudo-penis). Regardless of method, it is believed that the eggs must remain inside a warm-bodied host until nearly ready to hatch.
