Unidentified green-skinned species (The Plants of Plunder)

This unnamed humanoid species once accidentally brought dangerous plants into the hands of Human criminals.

Biology
Members of this species are humanoids with an overall Human-like build. However, they have green skin, and what appear to be very large eyes, or at least two white, rounded, triangular, downwards-pointing pieces of flesh coming down from the area where a Human's eyebrows would be. They do not appear to be conventional eyes, as they can be seen coming off of the aliens' faces. What is known is that their eyes at least consist of two small, black pupils, around the area where a Human's eyes would be. Other features include small upturned noses, small ears, and a lack of hair, at least atop their heads. Additionally, members of this species can shapeshift, able to take on a perfectly Human-like appearance.
