Zozoro-X are cave-dwelling worms brought aboard the Biological Science Labs for research. Their soft, worm-like bodies contain sticky feet similar to caterpillars that allow them to cling to cave walls and forage for food. Their bioluminescent rainbow-colored bodies are used for communication and mating. Zozoro-X also use the large, hair-like antennae on their heads to detect subtle changes in air pressure, allowing them to see further in the dark. These feelers also generate a mild defensive electrical field that will damage predators on contact. Their original uninfected forms are unknown.
