A reptohumanoid vessel was a starship utilized by a reptohumanoid species in the Delta Quadrant.
In 2372, this vessel came into conflict with USS Voyager and fired on it while both ships were in orbit of "Planet Hell". The reptohumanoid vessel was in orbit looking for a newborn hatchling on the surface of the planet. Fortunately, Voyager was able to rescue Tom Paris and Neelix from the surface before the reptohumanoid vessel could do more damage to them. (VOY: "Parturition")
The studio model for the "Reptile Alien Ship" was designed by Rick Sternbach in July 1995.
