The Regalians are a a sentient species. The Regalians are amphibious beings with large eyes on stalks and beak-like mouths. Their heads were often described as star-shaped, with their eyestalks, beaks, and cheek pouches forming a five-pointed star. Their lungs doubled as internal gills, and they had an acute sense of smell on land or in the water. Their green skins retained humidity, but a Regalian had to bathe in salt water every thirty hours or so, or their skin would crack open, resulting in internal and external bleeding and death.
