Zaigarchs are translucent jellyfish-like creatures that live in the magma chambers of their planet. They have bioluminescent organs that allow them to be seen in the dark recesses of their native caves, and the light they emit provides ocular nutrients to the other aquatic creatures nearby. They have no natural defenses and are very easy prey for larger animals. Zaigarchs reproduce asexually while being digested in other aquatic animals' stomaches.
