Nautolan
The Nautolans were a humanoid species from the planet Glee Anselm. They were amphibious, and adapted to survive in harsh environments. Nautolan society was largely peaceful, but they were at odds with the Anselmi, a related species also native to their home planet. Nautolans were amphibious, capable of breathing both air and water. They were known to be capable of surviving in extreme environments. Their skin could be green, blue, gray, purple, orange, or yellow, with red or green blood. One of their most notable features were their large, dark eyes, which were a product of evolution; through these eyes, they could spot details in lightless oceans.
Another notable detail were their long tendrils, which grew from their heads. These tendrils contained highly-sensitive olfactory receptors that were chemical-sensing, and most notably used to detect pheromones, allowing them to perceive expressions of emotion and other subtle changes in the body. Nautolans could translate pheromones emitted by other beings into an understanding of a being's emotional state. These head tresses could be severed, and while they were incapable of growing back, there were minimal long-term effects.
