Duthan

Duthans are a sapient spacefaring alien species from the planet Dutha, located about 2,000 light-years from Earth. They are members of the Galactic Federation.

Biology
Duthans are six-limbed centaur-like creatures with four hooved legs, a long tail and a humanoid torso. Their hands have five digits, consisting of three fingers and two opposable thumbs. They have mottled pinkish-brown skin, a pair of large brown eyes, and facial features consisting of slits, protuberances and fleshy petals. Their homeworld is warmer than Earth. Their skin doesn't react well to synthetic fibers.
