Neptunians are a species of seemingly-amphibious humanoids, presumably native to the planet Neptune, or one of its moons.


Neptunians are green-skinned, vaguely reptilian-like creatures with four-fingered hands, four-toed feet and bulging yellow eyes. Their hands and feet are webbed, suggesting an amphibious lifestyle. They also have a loose membrane hanging from their arms and connected to their bodies, which probably also aids in swimming.


  • This species was only ever featured as a Mego Star Trek action figure. It is notably the only alien in the line that never actually appeared in any of the Star Trek TV series or films.
