Xenoecology Has a complex multicellular ecology within the single melted eye-ocean. In the lightless depths many species have light-emitting organs of various kinds. One of the most spectacular species are the Eygloes, fast arthropod-like predators.

Most of Yanqiu is icebound; only a small circular ocean is liquid directly beneath the local star. This ocean holds almost all life on this world.
