Yinrih Womb-nest
Yinrih reproduce like salmon, only once in their lives, without physical contact, and via laying eggs, or rather a single very large egg. Unlike salmon, males also lay an egg (and yinrih don't die after laying, either.) When an equal number of male and female eggs are placed in a clutch together, a womb-nest forms.
A womb-nest is a highly derived egg-sac with its own simple heart and circulatory system. A central bus artery feeds oxygenated blood to the kits, and returning veins pass through a semi-permeable dermal layer to allow for gas exchange. The arrangement of kits in the womb nest is what gives Claravian* womb ships their name, as metabolic suspension capsules are arranged inside a womb ship in a similar manner to amnions in a womb nest.
* Claravian: of or relating to the Bright Way, from the Latin clara via (bright way).
