Ghen

Ghen are an aquatic humanoid species of sentient beings native to the planet Tau. Ghen are capable of forming higher societies, using advanced tools, complex communication, and problem-solving. Native to the equatorial regions of Tau, Ghen are capable of surviving both on land and in the water for extended periods of time. Ghen, which are generally shorter and stouter than humans, often standing at less than 1 meter in height, do not move well over terrestrial surfaces and build their dwellings and workplaces underwater.

Etymology
"Ghen" is the Ehlo word for "kin". The word first came into use by primitive Ghen around 300,000 years before the start of Kerbilization III.

Habitat and Population
Today, Ghen can be found living in every ocean in Tau. This is possible as a result of artificial climate control technologies of the Ghen's own invention. Ghen also learned to wear protective suits when on land in order to protect against Ogzor's harmful UV rays. Without the help of technology, Ghen cannot survive outside of the planet's tropics. Ghen can survive on land indefinitely, though this is seldom done.

Biology
Ghen are bipedal when on land and they stand at around 1 meter (closer to 3 feet on average) tall. They have stocky humanoid frames. Ghen traditionally have smooth and damp skin, similar to the skin of a lizard. While their hands mostly resemble flippers, Ghen do have 3 fingers on each hand. Fingers evolved as a result of needing to use tools for nearly 1 million years. Ghen do not have the ability to digest meat. They are strictly vegetarian. They have small eyes located between a large pair of fish-like lips. Their eyes are extremely sensitive to light prompting Ghen to wear protective goggles when on land. Ghen have a small triangular nose between their eyes. Their noses are weak and, as such, Ghen do not rely on them much. Ghen have ear holes on either side of their large head. Ghen have a head-spine (it is more profound on males than females) that sticks up like a Mohawk from their head. Ghen skin color varies by region. Equatorial Ghen often have vibrant blue-green skin while northern Ghen’s skin tends to be a pale blue.

Psychology
Ghen experience a full range of emotions and have the intelligence to actively seek out that which makes them happy. Ghen require mental stimulation to remain happy and will grow irritable when given nothing to do. Ghen form strong familial bonds and will often prioritize their loved one's well being over their own.
