Earth West 161,753,428 is a world in the the Anaerobic Belt which supports complex life. It contains "trees" which photosynthesize, intake carbon monoxide, and produce hydrogen sulphide. Creatures on this world include a UFO-shaped herd animal and a twelve-foot flying snake.
Maggie Kauffman's crew hypothesized that the creatures on this Earth had a kind of acidic blood, and the snake creature they discovered had managed to weaponize this biological feature to attack its prey.
According to the USS Neil A. Armstrong II's crew during their visit there, on this particular Earth, the sky is yellow, the shore is pale brown with streaks of scarlet and purple and the tree leaves are crimson.
